A simple pin-connected truss is loaded and supported as shown. The truss is constructed from three aluminum members, each having a cross-sectional area of A = 1860 mm2. Assume a = 1.7 m, b = 7.5 m, and c = 3.8 m. If P = 45 kN and Q = 90 kN, determine the normal stress in each member. L. Answers: OAB OBC OAC = (3 B MPa (C) MPa (T) MPa (T)
