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).

A load of P = 780 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,300 ksi] and has a square cross section with a width of 0.95 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 39 in., b = 15 in., and c = 8 in.

Two pieces of high-density polyethylene [E = 0.87 GPa] tubing are fitted together and firmly clamped at their ends. A load of 131 N is applied to the fitting. Tube (1) is 160 mm long, and tube (2) is 110 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 (1).

If the double-shear pin at D has a diameter of 0.600 in., an allowable shear strength of 14 ksi, and a factor of safety of 2.0, determine the maximum load P that can be applied to beam ABC. Let a = 32 in., b = 12 in., and c = 9 in.

If the double-shear pin at D has a diameter of 0.555 in., an allowable shear strength of 18 ksi, and a factor of safety of 1.5, determine the maximum load P that can be applied to beam ABC. Let a = 39 in., b = 16 in., and c = 9 in.

A short column is composed of two steel [E = 29,000 ksi, ν = 0.30] segments, each with a length of 5.9 in. Segment (1) is hollow with an outside diameter of 1.00 in. and a wall thickness of 0.16 in. Segment (2) is hollow with an outside diameter of 1.32 in. and a wall thickness of 0.16 in. How much shorter does the column become after a load of P = 880 lb is applied?

A load of P = 305 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 1.11 in. If the normal stress in bar (1) is limited to 12 ksi, determine the factor of safety for bar (1). Let a = 37 in., b = 12 in., and c = 9 in.

A load of P = 390 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.87 in. If the normal stress in bar (1) is limited to 15 ksi, determine the factor of safety for bar (1). Let a = 36 in., b = 12 in., and c = 10 in.

A load of P = 445 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,100 ksi] and has a square cross section with a width of 1.16 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 37 in., b = 15 in., and c = 11 in.

A 3D printed polymer rod measures 122.00 mm in length while on the heated print bed at 65.0°C. After cooling to room temperature at 20.8°C the rod measures 121.57 mm in length. Determine the coefficient of thermal expansion of the polymer.
