A load of P = 115 lb is applied to beam ABC. Bar (1) has a circular cross section with a diameter of 0.79 in. Determine the normal stress in bar (1). Let a = 33 in., b = 15 in., and c = 11 in.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,333 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 8 in., b = 14 in., c = 31 in., and d = 10 in. Assume there is no slack in the connections.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,743 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 14 in., c = 30 in., and d = 10 in. Assume there is no slack in the connections.
