A load of P = 495 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 36 in., b = 15 in., and c = 10 in.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,337 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 9 in., b = 14 in., c = 36 in., and d = 8 in. Assume there is no slack in the connections.

A load of P = 435 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 28 in., b = 12 in., and c = 8 in.

A force of P = 25 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 128,000 mm4 and a shear modulus of 1.9 GPa. Core (2) has a polar moment of inertia of 19,100 mm4 and a shear modulus of 1.3 GPa. Determine the torque produced in core (2). Let a = b = 215 mm.
