A vinyl [E = 2.65 GPa; v = 0.41] block with width b = 60 mm, depth d = 120 mm, and height h = 320 mm rests on a smooth rigid base. A load P is applied to a rigid plate that rests on top of the block. Calculate the change in the depth dimension d of the block after a load of P= 180 kN is applied. Rigid plate Answer: Ad = i Width b P Depth d Height h Rigid base mm
