The pin-connected assembly consists of aluminum rods (1) and (2) and steel rod (3). The aluminum rods each have a diameter of 19 mm and an elastic modulus of E = 69 GPa. The steel rod has a diameter of 22 mm and an elastic modulus of E= 190 GPa. Assume a = 4.8 m, b = 1.7 m, and c = 1.3 m. What is the magnitude of load P that is necessary to displace point A 9 mm to the left? a b A Answer: P = (3) B kN
