Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 80 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.

Three plates are connected with two bolts and transmit load P = 6.0 kN. Each plate is 5.1 mm thick, and each bolt has a diameter of 9.2 mm. Determine the average shear stress in the bolts.

_______ proteins would not span the entire lipid bilayer.
