A load of P = 160 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 38 in., b = 15 in., and c = 8 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.

A load of P = 375 lb is applied to beam ABC. Determine the normal force in bar (1). Let a = 35 in., b = 12 in., and c = 11 in.

A triangular piece of rubber is stretched causing A to move downward. Determine the magnitude of the shear strain that occurs at A when a = 37.9 mm, b = 75.8 mm, and c = 52.7 mm.

A Ro-Tel can weighs 0.71 lb and is 2.52 in. in diameter. A Libby’s can weighs 1.08 lb and is 2.90 in. in diameter. What is the largest bearing stress that occurs between the cans and the table? Assume each can has a smooth base and sits flat on the table.

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.

A Hunts can weighs 0.59 lb and is 2.54 in. in diameter. A Great Value can weighs 0.54 lb and is 2.56 in. in diameter. What is the largest bearing stress that occurs between the cans and the table? Assume each can has a smooth base and sits flat on the table.

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.

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.
