Using superposition, find the deflection of the steel shaft at A in the figure. Find the deflection at midspan. By what percentage do these two values differ? Take the magnitude of force (F) to be 315 lbf, w = 125 lbf/ft, and a = 12 in. y * 24 in F A 1.5 in-dia. shaft B x direction. direction. The magnitude of the deflection of the steel shaft at A is 0.1918 inch in the downward The magnitude of the deflection at midspan is 0.2183 inch in the downward The percentage difference is 13.83 * %.
