A vinyl [E = 2.80 GPa; v = 0.43] block with width b = 40 mm, depth d = 80 mm, and height h = 210 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 = 60 kN is applied. Rigid plate Answer: Ad = i Width b P Depth d Height h Rigid base mm

The composite bar is subjected to a normal force P = 7500 lb as shown in the figure. The section of the composite bar is composed of two hollow tubes and a solid steel core. Determine the axial stress developed in each bar. Use Ecu = 18 x 106 psi, Est = 30 x 106 psi, and Ebr = 16 x 106 psi.
