The disk shown in the figure rolls without slipping on the slope with an inclination angle of alpha = 28 degrees. The mass of the disk is 43 kg, its radius is R = 1.4 m, the arm of the rolling resistance is 0.012 m, and its instantaneous angular velocity is omega = 7 rad/s in the direction indicated in the figure.

A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg respectively. The centres of the mass of the discs are each 2.5mm from the axis of rotation. The radii to the centres of mass are at right angles. The shaft is carried in bearings C and D between A and B such that AC = 0.3m, AD = 0.9m and AB = 1.2m. It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed by adding a mass at a radius 25mm in a plane E.
