The torque wrench is used to tighten the nut on a bolt. If the dial indicates that a torque of 60 lb*ft is applied when the bolt is fully tightened, determine the force P acting at the handle and the distance s the needle moves along the scale. Assume only the portion AB of the beam distorts. The cross section is square having dimensions of 0.5 in. by 0.5 in. The material has an elastic modulus of E = 29(103) ksi. %3D A 12 in. 0.5 in. 0.5 in. 18 in.
