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.

A load of P = 155 lb is applied to beam ABC. Bar (1) has a circular cross section with a diameter of 0.88 in. Determine the normal stress in bar (1). Let a = 35 in., b = 14 in., and c = 11 in.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,045 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 8 in., b = 15 in., c = 34 in., and d = 9 in. Assume there is no slack in the connections.

If the length of a timber [E = 1,000 ksi] column cannot change by more than 0.045 in., determine the maximum load P that can be applied to the column. Let b = 4.25 in., d = 9.25 in., and L = 110 in.

A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 160 ksi] has a cross-sectional area of 1.2 in.2. Polymer (2) [E = 240 ksi] has a cross-sectional area of 1.2 in.2. After the shock absorber is loaded between steel plates by load P = 480 lb, determine the load carried by polymer (1).

If the length of a timber [E = 1,500 ksi] column cannot change by more than 0.045 in., determine the maximum load P that can be applied to the column. Let b = 6.00 in., d = 9.25 in., and L = 102 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 = 39.7 mm, b = 79.4 mm, and c = 54.4 mm.

If the length of a timber [E = 1,500 ksi] column cannot change by more than 0.045 in., determine the maximum load P that can be applied to the column. Let b = 6.00 in., d = 9.25 in., and L = 102 in.
