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

Problem: Two blocks for masses m1 and m2 are stacked on top of each other and placed on a frictionless, horizontal surface. The surfaces between two blocks is rough and has a coeff of static friction, us. A horiz push of magnitude, F, directed to the right is applied on the bottom block. A. Derive an expression for the maximum horizontal force, F, that can be applied on the bottom block, m1, before the top block m2, begins to slip....

Three blocks of mass ?1=?2=?3=1?? are stacked on a table as shown. The surfaces of the blocks and table are coated with Teflon and all have the same small coefficient of friction, ??=??=0.01. A force of 30N is applied straight down on the top mass as shown. a) Draw a free body diagram for each mass labelling all forces. b) Which direction might the bottom mass move and why? c) What is the acceleration of the top mass?

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?

The first cake has three layers with each one having a different top view: the bottom is a square, the middle is a hexagon, and the top is a circle. The height of each layer may vary. The second cake has three layers with a top view of concentric circles. All three layers have the same height. The diameter of the middle layer is 20% larger than the top layer, and the diameter of the bottom layer is 25% larger...

The composite walls of a building are made up of three materials. The inside layer of the walls is 1-cm thick wall board (kwb = 0.2 W/mK). The middle layer is 10 cm thick insulation (kI = 0.06 W/mK) and the outside layer is 3 cm of wood (kw = 0.15 W/mK). The total wall area is 350 m2. The outside air temperature is -10 oC and the inside air temperature is maintained at 20 oC. The inside and outside...
