The composite shaft, consisting of aluminum, copper, and steel sections, is subjected to the loading shown. Determine the displacement of B with respect to C. The cross-sectional area and modulus of elasticity for each section are shown in the figure. Neglect the size of the collars at B and C.

Review of fluid mechanics Example problems Hydrostatic Pressure: example problem Hydrostatic Pressure: example problem Two chambers with the same fluid at their base are separated by a 30-cm-diameter piston whose weight is 25N. Calculate the gage pressures in chambers A and B. Hydrostatic Pressure: example problem Consider a hydraulic jack being used in a car repair shop. The pistons have an area of A = 0.8 cm and A = 0.04 m . Hydraulic oil with a specific gravity of 0.870 is pumped 1 2 in as the small piston on the left side is pushed up and down, slowly raising the larger piston on the right side. A car that weighs 13,000 N is to be jacked up. (a) At the beginning, when both pistons are at the same elevation (h = 0), ca
