A rigid body is made of three identical thin rods, each with length L = 0.350 m, fastened together in the form of a letter H, as suggested by the gure here. The body is free to rotate about a horizontal axis that runs along the length of one of the legs of the H. The body is allowed to fall from rest from a position in which the plane of the H is horizontal. What is the angular speed of the body when the plane of the H is vertical? '3'\" \\ d} Number a Unit Ayo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 22 kg box as shown in the gure. The outer radius R of the device is 0.95 m, and the radius r of the hub is 0.41 m. When a constant horizontal force app of magnitude 140 N is applied to a rope wrapped around the outside of the device, the box, which is suspended from a rope wrapped around the hub, has an upward acceleration of magnitude 0.67 m/sz. What is the rotational inertia of the device about its axis of rotation? - Rigid lllUlllll Yn-yn shaped drn'rr Number n Units 0
