Two pieces of high-density polyethylene [E = 0.85 GPa] tubing are fitted together and firmly clamped at their ends. A load of 172 N is applied to the fitting. Tube (1) is 145 mm long, and tube (2) is 100 mm long. Both tubes have an outsider diameter of 23.0 mm and an inside diameter of 18.0 mm. Determine the load carried by tube (1).

A steel [E = 200 GPa] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 130 mm long. Determine the minimum diameter D required if this portion of the rod must hold a tensile load of 7.8 N without stretching more than 0.00115 mm.

A load of P = 275 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 1.04 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 32 in., b = 14 in., and c = 8 in.

A short column is composed of two steel [E = 29,000 ksi, ν = 0.30] segments, each with a length of 5.1 in. Segment (1) is hollow with an outside diameter of 1.00 in. and a wall thickness of 0.12 in. Segment (2) is hollow with an outside diameter of 1.24 in. and a wall thickness of 0.12 in. How much shorter does the column become after a load of P = 530 lb is applied?

A steel [E = 195 GPa] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 150 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 0.00130 mm.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 110 kN is applied to the assembly at A, two loads Q = 40 kN are applied at B, and two loads R = 130 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.24 m, E1 = 194 GPa, A1 = 0.0014 m2L2 = 0.42 m, E2 = 208 GPa, A2 = 0.0003 m2L3 = 0.30 m, E3 = 108 GPa, A3 = 0.0016 m2

A 3D printed polymer rod measures 115.00 mm in length while on the heated print bed at 67.0°C. After cooling to room temperature at 21.9°C the rod measures 114.69 mm in length. Determine the coefficient of thermal expansion of the polymer.

Two pieces of high-density polyethylene [E = 0.86 GPa] tubing are fitted together and firmly clamped at their ends. A load of 200 N is applied to the fitting. Tube (1) is 155 mm long, and tube (2) is 105 mm long. Both tubes have an outsider diameter of 22.0 mm and an inside diameter of 17.2 mm. Determine the load carried by tube (2).

A load of P = 485 lb is applied to beam ABC. Determine the normal force in bar (1). Let a = 28 in., b = 15 in., and c = 10 in.

Two pieces of high-density polyethylene [E = 0.95 GPa] tubing are fitted together and firmly clamped at their ends. A load of 196 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 23.0 mm and an inside diameter of 18.4 mm. Determine the load carried by tube (2).
