Two pieces of high-density polyethylene [E = 0.88 GPa] tubing are fitted together and firmly clamped at their ends. A load of 175 N is applied to the fitting. Tube (1) is 140 mm long, and tube (2) is 95 mm long. Both tubes have an outsider diameter of 22.0 mm and an inside diameter of 17.4 mm. Determine the load carried by tube (1).

A load of P = 260 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.97 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 38 in., b = 14 in., and c = 11 in.

A 3D printed polymer rod measures 142.00 mm in length while on the heated print bed at 58.5°C. After cooling to room temperature at 20.8°C the rod measures 141.53 mm in length. Determine the coefficient of thermal expansion of the polymer.

A steel [E = 185 GPa] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 160 mm long. Determine the minimum diameter D required if this portion of the rod must hold a tensile load of 9.8 N without stretching more than 0.00590 mm.
