Rigid bar ABC is supported by member (1), which has a cross-sectional area of 0.6 in.2, an elastic modulus of E = 10000 ksi, and a coefficient of thermal expansion of α = 12.1 × 10−6 /°F. Assume that a = 95 in., b = 40 in., and c = 135 in. After load P is applied to the rigid bar and the temperature rises 80°F, a strain gage affixed to member (1) measures a strain increase of 2902 με. Determine the magnitude of applied load P. Note: Assume the strain measuring system does not automatically compensate for temperature changes.
