A load of P = 710 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 1.06 in. Determine the magnitude of the normal strain in bar (1). Let a = 39 in., b = 13 in., and c = 10 in.

A Hunts can weighs 0.58 lb and is 2.51 in. in diameter. A Del Monte can weighs 0.59 lb and is 2.57 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 3,671 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 15 in., c = 33 in., and d = 10 in. Assume there is no slack in the connections.

A steel [E = 200 GPa; ν = 0.3; α = 11.2 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –11°C, the plate is 90 mm wide, 115 mm long, and 11 mm thick. The rectangular hole is 35 mm wide and 65 mm long. The circular holes have a diameter of 18 mm. At a final temperature of Tf = 41°C, determine the length of the plate.

An aluminum bar with a 1.50-in. gage length, 0.130-in. width, and 0.100-in. thickness is loaded in tension. At the proportional limit, a load of 350 lb elongates the gage length by 0.00372 in. and reduces the width by 0.000084 in. Determine the Poisson’s ratio.

A load of P = 425 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,700 ksi; ν = 0.34] and has a circular cross section with a diameter of 0.82 in. Determine the magnitude of the normal strain in bar (1). Let a = 29 in., b = 13 in., and c = 8 in.

A steel rod with a 1.50-in. gage length and a 0.130-in. diameter is loaded in tension. At the proportional limit, a load of 900 lb elongates the gage length by 0.00349 in. and reduces the diameter by 0.000088 in. Determine the Poisson’s ratio.

A load of P = 325 lb is applied to beam ABC. Determine the vertical ground reaction at B. Let a = 28 in., b = 15 in., and c = 9 in.

An upward load is applied to a circular rod that has a diameter of 10.25 mm. The rod is connected to the ground using a pin that has a diameter of 9.96 mm. If the average shear stress in the pin is limited to 165 MPa, determine the maximum load that can be applied to this connection.

A Hunts can weighs 0.64 lb and is 2.60 in. in diameter. A Del Monte can weighs 0.56 lb and is 2.54 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.
