Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,631 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 12 in., c = 36 in., and d = 9 in. Assume there is no slack in the connections.

An upward load is applied to a square rod that has a width of 10.24 mm. The rod is connected to the ground using a pin that has a diameter of 9.31 mm. If the average shear stress in the pin is limited to 185 MPa, determine the maximum load that can be applied to this connection.

A load of P = 425 lb is applied to beam ABC. Bar (1) is made of brass [E = 12,300 ksi; ν = 0.31] and has a circular cross section with a diameter of 0.78 in. Determine the magnitude of the normal strain in bar (1). Let a = 29 in., b = 13 in., and c = 10 in.

An aluminum bar with a 1.75-in. gage length, 0.220-in. width, and 0.085-in. thickness is loaded in tension. At the proportional limit, a load of 650 lb elongates the gage length by 0.00583 in. and reduces the width by 0.0002 in. Determine the Poisson’s ratio.

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.
