A simple pin-connected truss is loaded and supported as shown. The truss

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 = 1200 mm. Assume a = 2.3 m, b = 9.4 m, and c = 3.2 m. If P = 50 kN and Q = 70 kN, determine the normal stress in each member. P L. B Answers: a b AB = i MPa (C) OBC= i MPa (T) AC= i MPa (T)
