Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 90 mm, 110 mm, and 165 mm, respectively. After stretching, band A has a length of 110 mm, while bands B and C each have a length of 220 mm. Determine the minimum 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 170-mm long and has a diameter of 4.6 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 11.0 N.

What role does observer training play in aerial survey accuracy?

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 18 kN at pin B. Assume x1 = 3.3 m, x2 = 1.5 m, and y1 = 4.1 m. Determine the force in tie rod (1).

A load of 15 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 74 mm and the height is 140 mm. The size of the bearing plate is 94 mm. Determine the bearing stress between the plate and the beam.
