The cantilevered handle in the figure is made from mild steel that has been welded at the joints. The lengths are a = 6 in, b = 6 in, and c = 1.5 in. For Fx =0, Fy = 275 lbf, and F = 0. Use Castigliano's theorem to determine the vertical deflection (along the y-axis) at the tip. Note that when calculating the torsion strain energy of a noncircular cross section, J is not the polar moment of inertia. Instead, use Eq. 3-41 to determine an equivalent Jeq for the solid rectangular cross section of member BC. a 1-in dia. B in The vertical direction at the tip is in. Itin -india.
