Three blocks, each made of different materials, are going to be stacked on top of each other. One block is made of brass, another is made of iron, and a third is made of lead. Each block is a perfect cube: 1 m x 1 m x 1 m. Sam is worried about the weight of the blocks compressing each other. a. Come up with an algebraic equation for the total change in height for the stack of blocks (in other words – what’s the difference between its compressed height and 3 m?) in terms of the densities, Young’s moduli, and the dimensions of the blocks, as well as any needed physical constants. b. Which ordering of the blocks will produce the most compression? Using the densities found in this table and the Young’s moduli from this table, find the total change in height of this situation.

Densities: Iron=7.86e3, brass=8.49e3, lead=1.13e4

young's modulus: iron=21.0, brass=9.0, lead=1.6

Three identical 4 kg crates are stacked one on top of the other. You want to accelerate them as much as possible by pushing on the lower crate, but the forces of static friction between the surfaces of the crates max out at 25 N. What is the maximum acceleration you can achieve before the upper crates start to slide? And what's the maximum amount of force you can apply to the lower crate?
