A load of P = 7 N is applied to a hex wrench that has lengths a = 20 mm and b = 66 mm. Determine the torque applied to the set screw.

A torque of T = 265 lb·in. is applied to two pulleys and a copper-alloy shaft. Determine the minimum diameter of the shaft if its shear yield strength is 22 ksi.

If the length of a timber [E = 1,800 ksi] column cannot change by more than 0.045 in., determine the maximum load P that can be applied to the column. Let b = 4.75 in., d = 9.50 in., and L = 102 in.

Determine the magnitude of the largest bending moment (consider both positive and negative peaks) in the beam. Let M = 113 lb·ft, a = 2.6 ft, and b = 8.4 ft. Assume the beam cannot lift off of the supports.

A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 120 ksi] has a cross-sectional area of 1.4 in.2. Polymer (2) [E = 240 ksi] has a cross-sectional area of 1.4 in.2. After the shock absorber is loaded between steel plates by load P = 670 lb, determine the load carried by polymer (2).

A 25-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.2500 lb/in. Let a = 40 in. and b = 20 in.

A 3D printer is used to create a shock absorbed composed of two polymers. Polymer (1) [E = 260 ksi] has a cross-sectional area of 2.0 in.2. Polymer (2) [E = 240 ksi] has a cross-sectional area of 2.0 in.2. After the shock absorber is loaded between steel plates by load P = 475 lb, determine the load carried by polymer (2).

A 3D printed polymer rod measures 192.00 mm in length while on the heated print bed at 59.6°C. After cooling to room temperature at 20.1°C the rod measures 191.51 mm in length. Determine the coefficient of thermal expansion of the polymer.

A 31-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.1071 lb/in. Let a = 34 in. and b = 28 in.
