Three plates are connected with two bolts and transmit load P = 5.1 kN. Each plate is 5.0 mm thick, and each bolt has a diameter of 9.1 mm. Determine the average shear stress in the bolts.

The rigid beam BC is supported by rods (1) and (2). For a uniformly distributed load of w = 4.5 kN/m, determine the force in rod (1). Assume a = 3.70 m and L = 5.45 m.

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 75 mm, 110 mm, and 150 mm, respectively. After stretching, band A has a length of 90 mm, while bands B and C each have a length of 180 mm. Determine the minimum normal strain in the bands.

Two plates are connected with four bolts and transmit load P = 7.0 kN. Each plate is 5.9 mm thick, and each bolt has a diameter of 10.9 mm. Determine the average shear stress in the bolts.

The rigid beam BC is supported by rods (1) and (2). For a uniformly distributed load of w = 3.4 kN/m, determine the force in rod (1). Assume a = 3.40 m and L = 5.60 m.

A load of 17 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 80 mm and the height is 190 mm. The size of the bearing plate is 96 mm. Determine the bearing stress between the plate and the beam.

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 85 mm, 110 mm, and 160 mm, respectively. After stretching, band A has a length of 100 mm, while bands B and C each have a length of 200 mm. Determine the maximum normal strain in the bands.

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 150-mm long and has a diameter of 5.0 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 9.8 N.
