I hope you enjoy the image I made to facilitate my query. I wanted to add Thor as my force input but don't want any copyright infringement.. If I have a compression spring with a spring rate of K, on a fixed surface with an apple on top and a hammer.... If hammer applies force N, what does the apple see prior to the max deflection of the spring? What if instead of an apple I had put a solid steel cube or something that won't easily yield? Does the cube only get some of the force after the spring has bottomed out?
