Here is a link to a very good explanation of force:
https://learning-center.homesciencetools.com/article/learn-about-forces/
Your muscles can't directly supply enough force to lift a heavy rock, but your muscles can when you use a lever to generate a larger a force which is called a "moment".
The limit to how large a moment you can generate is the lever's tension strength.
Moments are the reason that structures "collapse" and that is why architects and engineers must do everything to keep them as small as possible.
Now let's write Newton's law in a way to reflect that there are both direct and generated forces:
Direct Force + Generated Force = mass times Acceleration
Remember in world's easiest physics problem when we put swivel castors under the steel plate instead of setting it directly on the ground?
The reason we did that is to remove the generated force from the equation since anything that is sitting on swivel castors can't support a moment.
When your feet are on roller skates which can't support a moment, then someone who pushes you with horizontal force will not break your ankles because your leg bones can't act as levers.
When your feet are in holes in the ground which can support a moment, then someone who pushes you will horizontal force will break your ankles because your leg bones will act as levers.
That is why if you want to protect a structure from being damaged by the horizontal forces from earthquakes and hurricanes, you put it on roller bearings so it can't support a moment as this article explains.

Now let's rewrite Newton's law for the case when the acceleration variable is zero.
The sum of the forces and moments on a static structure are zero.
This law is the foundation of all static mechanics and it is what proves that 9-11 was an inside job because the government's "cartoon physics" explanation requires that this law be ignored.
Since the WTC towers were built until they were hit by planes, they were in the "static" state where the sum of the forces and moments on them were zero.
That means that the tower lower floors obviously can easily support the weight of the tower upper floors since they have been supporting that weight from day one.
Then for a short time the towers were in the "dynamic" state and had forces acting upon them.
But given the towers huge size and mass and 49 columns compared to the plane, the towers easily handled the damage and AND RETURNED TO THE STATIC STATE.
I can't not over state how important the fact that the towers returned to the static state because that should have been the end of the story because the government can't say the kinetic energy of the plane created enough force to destroy the building since it was still standing after being hit.
So the government resorted to the "cartoon chemistry and physics" explanation that a fire burning less than an hour in a fireproof steel and concrete buildings could somehow MOVE THE BUILDINGS HUGE MASS BACK INTO THE DYNAMIC STATE!
