The pin-connected assembly consists of bronze rods (1) and (2) and steel rod (3). The
bronze rods each have a diameter of 12mm and an elastic modulus of E=120GPa. The
steel rod has a diameter of 18mm and an elastic modulus of E 210 GPa. Assume a=
2.0 m. b = 1.5 m, and c = 2.0 m. What is the magnitude of load P that is necessary to
displace point A 5 mm to the left?
