An aluminum rod with a 18.5-in. gage length and a 0.530-in. diameter is loaded in tension. At the proportional limit, a load of 17,000 lb elongates the gage length by 0.123 in. and reduces the diameter by 0.0011 in. Determine the Poisson’s ratio.

A Ro-Tel can weighs 0.78 lb and is 2.56 in. in diameter. A Libby’s can weighs 1.03 lb and is 2.86 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.

If rod (1) elongates 0.366 mm and rod (2) elongates 0.382 mm, determine how far downward E moves. Let a = 0.48 m and b = 0.78 m.

A load of P = 420 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 34 in., b = 16 in., and c = 10 in.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,545 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.

A load of P = 270 lb is applied to beam ABC. Determine the normal force in bar (1). Let a = 38 in., b = 15 in., and c = 10 in.

A Bush’s Best can weighs 1.15 lb and is 2.88 in. in diameter. A Libby’s can weighs 1.16 lb and is 2.93 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 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 = 305 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 29 in., b = 15 in., and c = 11 in.

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.
