A torque T is applied as shown to the long, hollow, tapered shaft AB of uniform thickness t. Derive an approximate expression for the angle of twist by replacing the tapered shaft by n cylindrical rings of equal length and of radius ri = (n + i – ½)(c/n), where i = 1, 2, . . ., n. Using for T, L, G, c, and t values of your choice, determine the percentage error in the approximate expression when (a) n = 4, (b) n = 8, (c) n = 20, and (d) n = 100.
