A steel [E = 215 GPa, ν = 0.265] 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 4.0 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 11.0 N.

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 90 mm, 120 mm, and 155 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 minimum normal strain in the bands.
