Question:

The cantilevered handle in Prob. 3–84, p. 140, is made from mild steel. Let Fy = 250 lbf, Fx = Fz = 0. Determine the angle of twist in bar OC, ignoring the fillets but including the changes in diameter along the 13-in effective length. Compare the angle of twist if the bar OC is simplified to be all of uniform 1-in diameter. Use superposition to determine the vertical deflection (along the y axis) at the tip, using the simplified bar OC.
