Three plates are connected with two bolts and transmit load P = 5.8 kN. Each plate is 4.1 mm thick, and each bolt has a diameter of 10.7 mm. Determine the average shear stress in the bolts.

A load of 14 kN is applied through a pin connection and a square bearing plate to the end of a beam that has a rectangular cross section. The base of the beam’s cross section is 92 mm and the height is 180 mm. The size of the bearing plate is 110 mm. Determine the bearing stress between the plate and the beam.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 35 kips, F2 = 10 kips, F3 = 23 kips, and F4 = 38 kips, determine the absolute value of the axial load in rod (2).

A square that was initially a x a in size is deformed into the following shape. If a = 29 mm, b = 11 mm, and c = 27 mm, determine the magnitude of the shear strain at C.

Two plates are connected with two bolts and transmit load P = 7.6 kN. Each plate is 4.9 mm thick, and each bolt has a diameter of 9.0 mm. Determine the average shear stress in the bolts.

Before an automotive engine is started, its timing belt has a length of 42.00 in. and a temperature of 70°F. At the engine operating temperature of 215°F, it is determined that the belt has elongated to 42.04 in. What is the coefficient of thermal expansion of the belt?

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.30 in. Segment (2) is hollow with an outside diameter of 1.58 in. and a wall thickness of 0.14 in. If segment (2) has a normal stress of 14 ksi, determine the normal stress in segment (1).
