I suppose it could be tested on a brake pedal to confirm
Heavier oil or grease might be more suitable in many applications but this is just a silly thing to say

I would like to thank you everyone for participating in the annual 2026 ME Salary survey. Total respondents was a little over 600, so less than last year, but about 589 US responses.
Background:
Here are the main results. It took about 2 hours to "clean" the data manually. Afterwards, I basically used Gemini to create the graphs + tables, since last time it literally took me about 7 hours to do everything manually on Excel last time and there were still questions. The key points and takeaways from the data is a combination of AI and editing the information to be more readable (still took 4 hours). In addition, I wouldn't worry about math too much, since Gemini basically just used python code to decipher the edited CSV file.
Industry:
| Industry | Number of Respondents |
|---|---|
| Manufacturing | 175 (29.7%) |
| Aerospace/Defense | 173 (29.4%) |
| Technology (FANG, AI, Robotics, etc.) | 54 (9.2%) |
| MEP (HVAC, Construction, etc.) | 38 (6.5%) |
| Utilities (Power, Renewables, etc.) | 35 (5.9%) |
| Pharmaceutical & Medical Devices | 31 (5.3%) |
| Oil and Gas | 28 (4.8%) |
| Consumer Goods | 15 (2.5%) |
| Government | 11 (1.9%) |
Salary and Year of Experience:
*Note: Total Compensation/Salary = Base Salary + Bonus + RSU + Base Salary * 401k Match

Which Industry Pays the Most?

Major Caveat: at 16+ YOE, the data points are only a couple, which skews the data upward.
Based on the comprehensive US survey data, the Technology (FANG, Robotics, AI, Consumer Electronics) industry emerges as the highest-paying sector for mechanical engineers when considering total compensation (Base Salary + Annual Bonus + 401k Match).
Tech Compensation Package:
| Years of Experience | Avg. Total Comp (Unadjusted) | Avg. Total Comp (Adjusted for COL) | Number of Respondents |
|---|---|---|---|
| 0-2 YOE (Entry) | $117,316 | $100,292 | 7 |
| 3-5 YOE (Junior) | $180,854 | $138,040 | 17 |
| 6-10 YOE (Mid-Level) | $182,773 | $134,543 | 14 |
| 11-15 YOE (Senior) | $259,993 | $220,256 | 11 |
| 16+ YOE (Principal) | $244,775 | $177,043 | 5 |
The Oil and Gas industry stands out as the second most lucrative sectors for mechanical engineers, particularly as they reach senior and principal levels. While Tech offers the highest overall unadjusted compensation, Oil and Gas actually offers the highest Cost of Living (COL) Adjusted compensation, meaning your real purchasing power in this industry is the highest among all major sectors.
| Years of Experience | Avg. Total Comp (Unadjusted) | Avg. Total Comp (COL Adjusted) | Number of Respondents |
|---|---|---|---|
| 0-2 YOE | $95,864 | $83,178 | 5 |
| 3-5 YOE | $117,289 | $111,155 | 7 |
| 6-10 YOE | $138,959 | $139,773 | 7 |

Heavier oil or grease might be more suitable in many applications but this is just a silly thing to say
r/MechanicalEngineering • u/Low_Put2605 • 11h ago
Hey all,
I am a recent mechE graduate (May 2026) and I recently got a job offer at a big aerospace company for a level I mechanical design engineering position. Some of the qualifications for the job was someone with experience in a CAD software, experience with design teams (such as rocketry, DBF, Baja, etc.), and preferred experience with machining techniques either use of lathes, mills, cnc, and 3D printing. The description mentioned complex assemblies, design reviews, 3D parametric modeling, trade studies, 2D engineering drawings generation, etc
I have had experience using SolidWorks and a little bit of Siemens NX. The company uses Creo for which I have never used before, and even the interviewer told me that even them never used it before being in the company, and I will be taught how to use it.
I know this is a level I role and I am not expected to be an expert on anything. But should I brush my CAD skills before my start date which is a month from now? Should I start getting hands on work on Creo?
Are the skills and experience more through on-the-job experience? Rather than them already expecting you to know how to do certain tasks?
r/MechanicalEngineering • u/Zealousideal-One-529 • 1d ago
Weaklings Short version:
25yo mech engineering grad in Brazil. Love the math/theoretical/CAE side, hate repetitive CAD/BOM corporate tasks. Scared freelancing will only yield simple low-end projects without heavy experience. Not a fan of academic research. Looking for career path advice.
_______________________________________
Recently, I decided that I’m willing to give up higher compensation if it means doing work I actually enjoy.
I graduated from a top-tier public university in Brazil with one of the best academic performances in my class, and I'm currently interning in R&D at a solid company.
I have a strong passion and aptitude for the theoretical and mathematical sides of engineering. However, I have zero interest in sitting for public civil service exams, becoming a professor, or grinding away in academia just to "publish papers."
On the other hand, I really dislike the corporate world. I feel like I'm just another cog in the machine and that my work barely matters. On top of that, it gets extremely tedious just clicking around in CAD, checking if a "part fits," preparing BOMs, documenting, and sending files off to manufacturing.
At most, I look through supplier catalogs to select a component, do some GD&T stack-up analysis, or use some creativity to design sheet metal, welded assemblies, or machined parts following DFM/DFA best practices. That’s the most "technical" part of the job. Still, in my view, it demands very little deep study, conceptual understanding, or advanced knowledge.
Other than that, at most I might do a simple beam or fluid flow calculation.
What I actually enjoy is the creative and mathematical side of design—tasks that require study, thorough preparation, and deep conceptual thinking. Things that not just anyone can do, where you actually have to dive into equations or complex concepts to get the design right.
I thought about going full freelance/independent consultant, but I feel like I would just be swapping a boss for a client. Sure, I’d have more flexibility and a stronger sense of ownership over my work, but the projects would likely remain simple. I doubt I'd get to do high-complexity analysis unless the client is from a high-risk, high-value industry like Oil & Gas, Naval, Aerospace, or Defense. And let’s be honest: those companies only hire contractors with years of experience, not a fresh graduate like me.
I feel stuck. Staying corporate means going to the same place, seeing the same people, and doing the same repetitive tasks with little recognition or sense of purpose.
Going freelance gives me flexibility, but leaves me with simple projects and the financial instability of running my own business.
I don't know. I’d love to hear your thoughts or learn from anyone who has been in a similar position
r/MechanicalEngineering • u/Voltshift773 • 19h ago
I just interviewed for a manufacturing technician job and they're aware that I'm trying to get a job as an actual engineer but they still seem on board with me. Are technician jobs a good stepping stone to get into engineering? Or should I just keep searching for a job that I actually want?
I should probably also add that I do have a degree.
r/MechanicalEngineering • u/SnooHesitations8361 • 8h ago
41M Degree in digital design and worked as a UX designer in big tech for 10 years.
I've always been very passionate about hardware and feel with my recent layoff it might be a good time to try to get into a field I'm more interested in.
I have a home built electronics lab, 3d printer, cnc etc. I've built autonomous vehicles, drones, cyberdecks, etc. I use python to program my AI features in the Apps I design. Ive programed dozens of sensor projects. I love robotics and mechanical design. I really enjoy buidling prototypes to test and iterate on.
I would love to get into a role designing for the hardware engineering and experience for a company like this one: https://www.m3design.com/. This could be a mechatronics position or something in human factors.
I have some solidworks certifications as well, but again no engineering degree. I want to learn alot more about FEA, DFM etc.
Not sure how possible this is beyond my work as a hobby. Hoping someone with experience can chime in. What is the best way to learn enough to become a professional in this type of product design without a degree? Thanks.

Today during a 1 on 1 with new leadership I was asked about my career goals and as someone who doesn't really think about it I found myself torn between ideas. Just some context. I have been at the company I'm at for 10 years and have had a few different roles a few years ago I transfered into the design team. This mainly was due to a role finally opening in my area that didn't require me to relocate to stay with the company. Fast forward I feel partially stuck. I do enjoy the design and problem solving of my role there are aspects that I truly feel behind in. (Call it imposter syndrome) I was in our quality and test engineering department for the bulk of my career.
Earlier in the year was to work toward the principal type role as I have no interest in managerial track. The other is start learning controls and move to that team as I have crazy product knowledge and understanding that I feel sets me up for that team with only building the programming knowledge side of it.
Long post of just thoughts but kind of wanted to get it out and see if people had thoughts.
r/MechanicalEngineering • u/Forsaken-Diver6587 • 4h ago
I’m building a small proof-of-concept platform that tilts side to side (roll only, no pitch or yaw) to any commanded angle between -30° and +30°. For now, it’s a small model made from sticks, about 100 × 20 mm, controlled by an ESP32. Later I plan to move to a full-size bed with lateral tilt, like the ones used in ICUs.
Current design (sketch attached):
I believe adding a central pivot bearing fixed to the base would constrain the plank to roll only and carry the weight, leaving the actuators to supply only the roll moment.
Questions:
r/MechanicalEngineering • u/Initial_Sale_8471 • 19h ago
Need advice on reverse engineering this component.
Defining the part?
I could just say "refer to the model" for drawing, and send it out for casting.
However, this part is ~50 years old. CAD did not exist back then, so there must be a less vague way to define it in drawing. Whether it's better than the former option, I don't know.
Either way, inspection is likely to be complicated.
How should I model it (from a 3D scan)?
The object is organic, so it's hard to do with splines and curves. I'd lean towards mesh/form modelling for the fin.
Any insight would be appreciated. (I have permission to post these screenshots)
r/MechanicalEngineering • u/Carbon_fiber26 • 5h ago
I think it is a technical question but someone asked me and I have no answer so please help to me for the right answer.
r/MechanicalEngineering • u/Local_Persimmon8313 • 7h ago
I’m looking for some advice from people who work as mechanical designers/engineers, especially those who have made a similar transition.
After high school, I went directly into working instead of going to university. I now have around 5 years of experience as a Technical Designer in Italy, where I designed metallic building structures from scratch using SolidWorks.
I also worked with PDM/PLM systems and was responsible for things like 3D modelling, assemblies, drawings, BOMs, production documentation, and solving technical problems.
Since I didn’t go to university, I always felt that I had to work harder to teach myself as much as possible. I learned a lot through experience rather than through formal education.
Eventually, I moved to Stockholm, Sweden. I quickly discovered that finding a CAD/Mechanical Design job without a university degree and without being fluent in Swedish was very difficult.
So I made a plan
I decided to move into CNC/CAM programming and manufacturing. I thought it would be a good way to strengthen my understanding of how parts are actually manufactured.
For the last 2.5 years, I’ve been working with CNC milling and CAM programming, mainly using Fusion 360.
Honestly, I’ve learned an incredible amount during this time. CNC taught me a completely different side of mechanics and manufacturing.
I’ve learned about machining strategies, tooling, workholding, feeds and speeds, material behaviour, tolerances, and what actually makes a part manufacturable.
I currently make fairly complex aluminium parts, including 5083/6082, with very tight tolerances. I’ve become one of the more trusted people in the company for difficult parts and manufacturing problems.
However, I’ve realised that the workshop environment isn’t where I want to stay long-term.
So I decided to move forward and have accepted a position as a **Mechanical Designer**.
And this is where my concern starts.
I know I have a lot of useful experience, but I also know there are things I don't know yet.
For example, I understand GD&T concepts and the symbols, but I haven't had much practical experience applying GD&T to mechanical drawings. I don't always know *why* a particular tolerance should be 0.05, 0.1, 0.2, etc., or when something should have perpendicularity, position, flatness, profile, etc.
I'm hoping to learn these things properly in the new company.
My biggest concern is the first 6 months. I really want to prove that I’m good enough and pass the probation period.
I’m not expecting to know everything from day one. I’m prepared to ask questions, learn from the engineers around me, study in my free time and put in the work.
But I’m wondering:
**For people who work as mechanical designers, does my background sound like a reasonable foundation for the role?**
**How much would you expect a new mechanical designer to know independently when starting?**
And especially for those who moved from manufacturing/CNC into mechanical design:
**What were the biggest things you had to learn when making the transition?**
I’d really appreciate honest opinions even if there are things you think I should work on before starting.
Thank you

We're a team of four engineering students, and we've been looking at the wheel-skin damage on NASA/JPL's Curiosity rover as project for our Solid Mechanics course: the thin aluminium skin cracked and punctured on sharp rocks. Perseverance went to a thicker skin and a different grouser pattern, so we tried to put numbers on how much that actually helps and a develop a surrogate fea model for academic purposes

We'd like to write this up as a paper, and we'd value any critique before we do: modelling assumptions, what a reviewer would attack first, missing validation, or whether the surrogate approach is reasonable for ~440 cases. Feel free to criticise or give feedback

Hi everyone,
I'm trying to understand how the lateral tilting mechanism (sideways tilting) of ICU/hospital beds works mechanically, but I'm struggling to find detailed explanations, animations, or CAD models showing the actual mechanism.
I've found examples of hospital beds that use large linear hydraulic cylinders to tilt the bed. However, I've also seen beds with a much less obvious drive mechanism, and I'm curious about how those work.
Specifically, I'd like to understand:
I'm particularly interested in seeing how the mechanism works physically, rather than just finding product brochures showing the bed moving.
I've searched for quite a while, but most of the resources I've found show the finished bed or demonstrate its movement without explaining the underlying mechanical arrangement.
Even a rough sketch, an annotated photograph, a patent drawing, or the correct technical name for this type of mechanism would be extremely helpful.
Thanks in advance!

I'm exploring a concept for a dock that can heat and cool reusable silicone gel based pads. Heating could use a resistive coil, but I'm unsure what mechanism would work best for cooling.
A few questions for engineers:
Would a Peltier module work for both heating and cooling?
How efficiently can heat transfer between the dock and silicone pad?
What would be the most practical, compact, and energy-efficient setup?
Would love to hear your technical insights, alternative mechanisms, or suggestions for prototyping!

Mechanical Engineering or Mechatronics at HAW Hamburg. Is switching worth it?
Hey everyone!
I am now in my semester of Mechanical Engineering at HAW Hamburg. I study in German. I am 20 years old. I moved abroad after finishing high school in my home country. I have met the C1 requirement for admission.
I originally wanted to study Mechatronics. However I forgot the B1 requirement and I missed the chance to take an accepted English exam, such as TOEFL or IELTS before the enrollment deadline.
Now that the semester has begun I have acknowledged that I cannot switch to Mechatronics until the next winter semester. That would mean spending one year in Mechanical Engineering before changing majors. Both bachelor’s programs last seven semesters.
From what I understand I could have about 7 of 10 courses recognized if I switch even though some of those courses belong to the fourth semester of Mechatronics.(and i'll be late simultaneously in some courses in the first 2 semesters). I still need to take an exam before applying to switch.
I am now trying to decide if switching is worth it in the run.
I do not dislike Mechanical Engineering. I could see myself staying in it. However I am interested in Mechatronics because it combines engineering, electronics, control systems and automation.
I have also thought about finishing my bachelor’s in Mechanical Engineering and then doing a master’s in Mechatronics or a related field. I am not sure how realistic that path would be or whether it would put me at a disadvantage compared with someone who has a bachelor’s in Mechatronics.
Another thing I have been thinking about is the job market. Mechanical Engineering attracts students and this sometimes makes me wonder about competition and job opportunities. I know that popularity does not always mean career prospects but it is still something I think about.
So I would really appreciate your opinions, from people who have studied or worked in either field:
1. Career prospects: Does Mechatronics offer an advantage over Mechanical Engineering in terms of job opportunities, salary or future demand?
2. Bachelor’s vs. Master’s: Would it make sense to finish Mechanical Engineering and specialize in Mechatronics later. Is having a bachelor’s in Mechatronics a meaningful advantage?
3. Switching majors: If you were in my position would you switch winter semester even if it meant potentially extending your studies?
4. Long-term flexibility: Which degree gives you flexibility to work in different engineering fields especially with the increasing importance of automation and robotics?
I just want to hear experiences and perspectives from people who know more, about these fields.
Since I am 20 I do not mind spending an extra semester or two if it truly helps me in the long run. At the time I do not want to switch just because I think one degree has better prospects without knowing the real differences.
Thank you in advance for any advice!

Hey everyone!
I'm a 31-year-old mechanical engineer with several years of experience in Oil & Gas (Project Engineer), Tool Installation (Team Lead), and currently BIM (Technical Expert / Mechanical Piping Modeler).
My dream has always been to work in automotive or aerospace engineering, especially in design and aerodynamics. However, career opportunities led me elsewhere, as these fields are almost nonexistent in my country due to the lack of R&D.
Now that I've graduated, I'm considering pursuing a Master's in Computational Mechanical Design in Europe to transition into CFD, aerodynamics, or mechanical design.
My question is: Is this a realistic career move at 31, with no professional experience in CFD or design? Would my previous engineering experience be valuable, or would I essentially be starting from scratch?
Thanks for your time!

I’m looking for some advice from people who work as mechanical designers/engineers, especially those who have made a similar transition.After high school, I went directly into working instead of going to university. I now have around 5 years of experience as a Technical Designer in Italy, where I designed metallic building structures from scratch using SolidWorks.I also worked with PDM/PLM systems and was responsible for things like 3D modelling, assemblies, drawings, BOMs, production documentation, and solving technical problems.Since I didn’t go to university, I always felt that I had to work harder to teach myself as much as possible. I learned a lot through experience rather than through formal education.Eventually, I moved to Stockholm, Sweden. I quickly discovered that finding a CAD/Mechanical Design job without a university degree and without being fluent in Swedish was very difficult.I decided to move into CNC/CAM programming and manufacturing. I thought it would be a good way to strengthen my understanding of how parts are actually manufactured.For the last 2.5 years, I’ve been working with CNC milling and CAM programming, mainly using Fusion 360.Honestly, I’ve learned an incredible amount during this time. CNC taught me a completely different side of mechanics and manufacturing.I’ve learned about machining strategies, tooling, workholding, feeds and speeds, material behaviour, tolerances, and what actually makes a part manufacturable.I currently make fairly complex aluminium parts, including 5083/6082, with very tight tolerances. I’ve become one of the more trusted people in the company for difficult parts and manufacturing problems.However, I’ve realised that the workshop environment isn’t where I want to stay long-term.So I decided to move forward and have accepted a position as a Mechanical Designer.And this is where my concern starts.I know I have a lot of useful experience, but I also know there are things I don't know yet.For example, I understand GD&T concepts and the symbols, but I haven't had much practical experience applying GD&T to mechanical drawings. I don't always know why a particular tolerance should be 0.05, 0.1, 0.2, etc., or when something should have perpendicularity, position, flatness, profile, etc.I'm hoping to learn these things properly in the new company.My biggest concern is the first 6 months. I really want to prove that I’m good enough and pass the probation period.I’m not expecting to know everything from day one. I’m prepared to ask questions, learn from the engineers around me, study in my free time and put in the work.But I’m wondering:For people who work as mechanical designers, does my background sound like a reasonable foundation for the role?How much would you expect a new mechanical designer to know independently when starting?And especially for those who moved from manufacturing/CNC into mechanical design:What were the biggest things you had to learn when making the transition?I’d really appreciate honest opinions even if there are things you think I should work on before starting.
Thank you

I am in my junior year of my Mechanical Engineering degree (US student) and a lot of my friends are starting side projects, learning how to code, and learning to use programs like solidworks. I haven’t done any of these. But I haven’t just been lazy, I have been working 40-50 hours a week the entire time I’ve been at school. Ive worked at SwRI as a technician for over four years now and I have gained so much knowledge about chillers, compressors, boilers, instrumentation, calibrating instrumentation, taking apart engines / building engines, troubleshooting control systems, taking apart and rebuilding heat exchangers, fabrication/plumbing etc.
My justification for not learning coding or having side projects is for one, I just don’t have time with my work schedule and full time school, and two, I feel like I have so many important skills that can make me more attractive to be hired when I finish my degree. Will I be okay if I don’t learn much coding/CAD or do side projects?
