A load of P = 450 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,600 ksi] and has a circular cross section with a diameter of 1.04 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 38 in., b = 13 in., and c = 11 in.

Two pieces of high-density polyethylene [E = 0.94 GPa] tubing are bonded together and support load P = 102 N. Both tubes are 150 mm long. The outer tube has an outsider diameter of 23.0 mm and an inside diameter of 18.4 mm. The inner tube has an outside diameter of 18.4 mm and an inside diameter of 14.4 mm. Determine the load carried by the inner tube.

The pin-connected structure is subjected to a load P=242 N as shown. Inclined member (1) is connected to rigid member ABC. Determine the magnitude of the resultant force at pin A.

An aluminum [E = 10,000 ksi] control rod with a circular cross section must not stretch more than 0.37 in. when the tension in the rod is 2,300 lb. If the diameter of the rod is 0.378 in., determine the maximum length of the rod.

The pin-connected structure is subjected to a load P=268 N as shown. Inclined member (1) is connected to rigid member ABC. Determine the magnitude of the resultant force at pin A.
