Engineering Mechanics - Dynamics Chapter 13 Problem 13-75 The rotational speed of the disk is controlled by a smooth contact arm AB of mass M which is spring-mounted on the disk.When the disk is at rest , the center of mass G of the arm is located distance d from the center O , and the preset compression in the spring is a . If the initial gap between B and the contact at C is b , determine the (controlling) speed v G of the arm’s mass center, G , which will close the gap. The disk rotates in the horizontal plane. The spring has a stiffness k and its ends are attached to the contact arm at D and to the disk at E . Given: M 30 gm = a 20 mm
