A uniform disk of mass m = 4 kg and radius r = 150 mm is supported by a belt ABCD that is bolted to the disk at B and C. If the belt suddenly breaks at a point located between A and B, draw the FBD and KD for the disk immediately after the break.

A cage of mass 2500 kg is raised and lowered by a winding drum of 1.5 m diameter. A brake drum
is attached to the winding drum and the combined mass of the drums is 1000 kg and their radius of
gyration is 1.2 m. The maximum speed of descent is 6 m/s and when descending at this speed, the
brake must be capable of stopping the load in 6 m. Find 1. the tension of the rope during stopping
at the above rate, 2. the friction torque necessary at the brake, neglecting the inertia of the rope, and
3. In a descent of 30 m, the load starts from rest and falls freely until its speed is 6 m/s. The brake
is then applied and the speed is kept constant at 6 m/s until the load is 10 m from the bottom. The
brake is then tightened so as to give uniform retardation, and the load is brought to rest at the
bottom. Find the total time of descent.

The figure shows a trolley of mass 10 kg that can move freely along a smooth fixed horizontal rail driven by a horizontal applied force, F. Pivoted to the trolley at A is a rigid link AB of mass 2 kg, length 1.5 m and inertia 0.38 kgm² about the centre of
gravity of the link, which is located at the midpoint. The link is driven by a motor mounted on the trolley which applies an anticlockwise torque T to the link.
When the link is at 30° to the horizontal and the mechanism is undergoing the motion shown in the figure determine the magnitude of the reaction force acting on the link at point A in the x and y directions. The positive sense for x and y is given in the
figure, and gravity can be assumed to be 10 m/s².
