Q/In the given figure, a horizontal rigid is supported by a pin connection at point A and an axial member (1) at point C. Member (1) has a cross-sectional area of A1 = 1.5 in.2, an elastic modulus of E1 = 10600 ksi, and a coefficient of thermal expansion of α1 = 12 *10-6/°F. Upon applying a load P and simultaneously increasing the temperature by ΔT = 80 °F, the strain in element (1) is observed to increase by ε1 = 1700 με. What is the magnitude of force P? [a = 45 in., b = 32 in., L1 = 55 in.] The answer in kips ?
