Engineering Mechanics - Dynamics Chapter 21 Problem 21-46 The conical pendulum consists of a bar of mass m and length L that is supported by the pin at its end A . If the pin is subjected to a rotation ω , determine the angle θ that the bar makes with the vertical as it rotates. Solution: I x I z = 1 3 mL 2 = I y 0 = x 0 = y cos () = z sin = ' x 0 = ' y 0 = ' z 0 = Σ M x I x ' x I y I z y x = m g L 2 sin 00 1 3 2 cos sin = g 2 1 3 L ω 2 cos = acos 3 g 2 L 2 = Problem 21-47 The plate of weight W is mounted on the shaft
