A load of P = 345 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.85 in. If the normal stress in bar (1) is limited to 13 ksi, determine the factor of safety for bar (1). Let a = 40 in., b = 14 in., and c = 9 in.

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 short column is composed of two steel [E = 30,000 ksi, ν = 0.30] segments, each with a length of 5.8 in. Segment (1) is hollow with an outside diameter of 1.00 in. and a wall thickness of 0.18 in. Segment (2) is hollow with an outside diameter of 1.36 in. and a wall thickness of 0.18 in. How much shorter does the column become after a load of P = 880 lb is applied?

A 3D printed polymer rod measures 157.00 mm in length while on the heated print bed at 51.9°C. After cooling to room temperature at 22.0°C the rod measures 156.66 mm in length. Determine the coefficient of thermal expansion of the polymer.

Two pieces of high-density polyethylene [E = 0.92 GPa] tubing are fitted together and firmly clamped at their ends. A load of 116 N is applied to the fitting. Tube (1) is 150 mm long, and tube (2) is 100 mm long. Both tubes have an outsider diameter of 21.0 mm and an inside diameter of 16.0 mm. Determine the load carried by tube (2).

A steel [E = 195 GPa] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 165 mm long. Determine the minimum diameter D required if this portion of the rod must hold a tensile load of 12.0 N without stretching more than 0.00520 mm.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 120 kN is applied to the assembly at A, two loads Q = 50 kN are applied at B, and two loads R = 160 kN are applied at C.
