Engineering Mechanics - Dynamics Chapter 18 ω Find () = 11.0 rad s = Problem 18-23 The disk of mass m d is originally at rest, and the spring holds it in equilibrium. A couple moment M is then applied to the disk as shown. Determine how far the center of mass of the disk travels down along the incline, measured from the equilibrium position, before it stops. The disk rolls without slipping. Given: m d 20 kg = M 30 N m = k 150 N m = θ 30 deg = r 0.2 m = g 9.81 m s 2 = Solution: Guess d 3m = Initial stretch in the spring
