A cube with a side length of 10cm is made up of aluminum metal (E= 25 x 10^9 N/m2) A horizontal shear force of 50000 N is applied to this cube. (a) How far will the top of the cube move in the horizontal directin relative to the bottom of the cube? (b) What is the shear stress appied to the cube? (c) Calculate the shear strain on the cube.​

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
