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.

A load of 37 kN is applied to a circular shape that protrudes 14.4 mm from a brass plate. The circular shape has a diameter of 17.2 mm. Determine the average shear stress between the plate and the protrusion.

A load of 20 kN is applied to a circular shape that protrudes 15.8 mm from a brass plate. The circular shape has a diameter of 16.3 mm. Determine the average shear stress between the plate and the protrusion.

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 Hunts can weighs 0.65 lb and is 2.58 in. in diameter. A Great Value can weighs 0.54 lb and is 2.50 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 the normal stress in rod (1) is limited to 230 MPa and the required factor of safety is 2.1, determine the maximum load P that can be applied to rod (2). Let a = 0.43 m, b = 0.82 m, and the cross-sectional area of rod (1) be 195 mm2.

A steel rod with a 1.75-in. gage length and a 0.190-in. diameter is loaded in tension. At the proportional limit, a load of 1,100 lb elongates the gage length by 0.00207 in. and reduces the diameter by 0.000065 in. Determine the Poisson’s ratio.

A load of P = 200 lb is applied to beam ABC. Bar (1) has a circular cross section with a diameter of 0.85 in. Determine the normal stress in bar (1). Let a = 35 in., b = 13 in., and c = 8 in.

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.
