Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,545 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 13 in., c = 38 in., and d = 11 in. Assume there is no slack in the connections.

An upward load is applied to a square rod that has a width of 10.71 mm. The rod is connected to the ground using a pin that has a diameter of 9.16 mm. If the average shear stress in the pin is limited to 200 MPa, determine the maximum load that can be applied to this connection.

A load of P = 475 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,300 ksi; ν = 0.32] and has a circular cross section with a diameter of 0.76 in. Determine the magnitude of the normal strain in bar (1). Let a = 38 in., b = 15 in., and c = 10 in.
