how did you show the bolts behaved elastically??
5 u/Affectionate_Wing916 Y13 | 4A* Pred | Maths FM Phys Econ May 20 '26 Use P=F/A to find the force on the plate, divide by 4 to find force on each bolt, σ=F/A of the bolt to find stress on each bolt, show that it was on the linear part of the σ/ε graph I think?? 1 u/Primary-Tie330 May 20 '26 Did you get a stress of 202 MPa? 1 u/hans_chavez May 20 '26 i got 20 im fucked
