A load of P = 780 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,700 ksi; ν = 0.33] and has a circular cross section with a diameter of 0.97 in. Determine the magnitude of the normal strain in bar (1). Let a = 37 in., b = 12 in., and c = 9 in.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,275 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 8 in., b = 12 in., c = 35 in., and d = 11 in. Assume there is no slack in the connections.

An upward load is applied to a circular rod that has a diameter of 10.63 mm. The rod is connected to the ground using a pin that has a diameter of 9.55 mm. If the average shear stress in the pin is limited to 140 MPa, determine the maximum load that can be applied to this connection.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,567 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 8 in., b = 16 in., c = 39 in., and d = 9 in. Assume there is no slack in the connections.
