Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 75 mm, 115 mm, and 165 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 maximum normal strain in the bands.

A steel [E = 200 GPa, ν = 0.293] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 165-mm long and has a diameter of 4.4 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 11.0 N.

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 = 2.90 m and L = 4.10 m.

A steel [E = 205 GPa, ν = 0.259] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 165-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 11.0 N.

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 10 kN at pin B. Assume x1 = 3.4 m, x2 = 1.9 m, and y1 = 4.5 m. Determine the force in tie rod (1).

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 32 kips, F2 = 12 kips, F3 = 25 kips, and F4 = 36 kips, determine the absolute value of the axial load in rod (2).

A steel [E = 190 GPa, ν = 0.259] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 170-mm long and has a diameter of 4.2 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 9.8 N.

A qualitative researcher returns preliminary findings to participants for confirmation. Which strategy is being used? 

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.

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 12 kN at pin B. Assume x1 = 2.6 m, x2 = 2.1 m, and y1 = 4.4 m. Determine the force in tie rod (1).
