Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video. Rigid bar ABC is supported by member (1), which has a cross-sectional area of 0.7 in.?, an elastic modulus of E = 10600 ksi, and a coefficient of thermal expansion of a = 12.5 x 10-6 /°F. Assume that a = 95 in., b = 50 in., and c 170 in. After load Pis applied to the rigid bar and the temperature rises 50°F, a strain gage affixed to member (1) measures a strain increase of 2104 uE. Determine the magnitude of applied load P. Note: Assume the strain measuring system does not automatically compensate for temperature changes. DO Strain gage (1) A C a b Answer: P = kips
