Determine the maximum load P that can be applied to the beam if the bearing plates A and B have square cross sections of 2 in. * 2 in. and 4 in. * 4 in., respectively, and the allowable bearing stress for the material is (sb)allow = 400 psi.

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
