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.

Two pieces of high-density polyethylene [E = 0.87 GPa] tubing are fitted together and firmly clamped at their ends. A load of 179 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 15.6 mm. Determine the load carried by tube (1).

A short column is composed of two steel [E = 29,000 ksi, ν = 0.29] segments, each with a length of 4.8 in. Segment (1) is hollow with an outside diameter of 1.10 in. and a wall thickness of 0.17 in. Segment (2) is hollow with an outside diameter of 1.44 in. and a wall thickness of 0.17 in. How much shorter does the column become after a load of P = 650 lb is applied?

A load of P = 645 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,600 ksi] and has a square cross section with a width of 0.88 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 33 in., b = 14 in., and c = 10 in.

A 3D printed polymer rod measures 184.00 mm in length while on the heated print bed at 66.8°C. After cooling to room temperature at 21.3°C the rod measures 183.36 mm in length. Determine the coefficient of thermal expansion of the polymer.

A short column is composed of two steel [E = 30,000 ksi, ν = 0.29] segments, each with a length of 5.1 in. Segment (1) is hollow with an outside diameter of 1.30 in. and a wall thickness of 0.12 in. Segment (2) is hollow with an outside diameter of 1.54 in. and a wall thickness of 0.12 in. How much shorter does the column become after a load of P = 760 lb is applied?

Two pieces of high-density polyethylene [E = 0.95 GPa] tubing are fitted together and firmly clamped at their ends. A load of 112 N is applied to the fitting. Tube (1) is 140 mm long, and tube (2) is 100 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).

Two pieces of high-density polyethylene [E = 0.86 GPa] tubing are fitted together and firmly clamped at their ends. A load of 115 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 23.0 mm and an inside diameter of 17.2 mm. Determine the load carried by tube (2).
