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 340 lbf, w= 130 lbf/ft, and a = 14 in. + F 24 in 15in A 1.5 in-dia. shaft B I The magnitude of the deflection of the steel shaft at A is The magnitude of the deflection at midspan is 0.0016 The percentage difference is 33.33 %. 0.0027 inch in the downward direction. inch in the downward direction.
