I need to calculate the force of a weight bearing down on a smaller object, constraining it from expansion.
The weight bearing down has a much bigger surface area than the smaller object.
I know the mass of the weight.
I know the surface area of the smaller object.
What else do I need to know in order to calculate the force bearing down on the small object?
What I mean is, what do I need to know in order to calculate what the force bearing down on that smaller object is?
I think I might need to know about the acceleration of gravity (9.8 m s^-2), but I'm not sure how that applies if I don't know the dimensions of the larger object.
I know that F=ma, but I can't visualise how that applies to an object bearing down on an object with a smaller surface area.
