Engineering Mechanics - Dynamics Chapter 21 Problem 21-54 The thin rod has mass m rod and total length L . Only half of the rod is visible in the figure. It is rotating about its midpoint at a constant rate θ ' , while the table to which its axle A is fastened is rotating at angular velocity ω . Determine the x, y, z moment components which the axle exerts on the rod when the rod is in position θ . Given: m rod 0.8 kg = L 150 mm = ' 6 rad s = 2 rad s = Solution: I A m rod L 2 12 = ω v sin () cos ' = α sin cos 0 ω v × = ωθ ' cos ' sin 0 = MI mat αω v I mat ω v × + = M x M y M z 0 0 0 0 I A 0 0 0 I A ' cos ' sin 0 × sin cos '
