A polymer cylinder (2) is clamped between rigid heads by two steel bolts (1). The steel [E = 29,000 ksi; a = 6.5×10-6/°F] bolts have a diameter of 0.45 in. The polymer [E = 350 ksi; a = 37.2x 10-6/°F] cylinder has an outside diameter of 6.0 in. and a wall thickness of 0.70 in. Assume a = 23 in. and b = 31 in. If the temperature of this assembly changes by AT = 130°F, determine: (a) the normal stress in the polymer cylinder. (b) the normal strain in the polymer cylinder. (c) the normal strain in the steel bolts.
