Question
Example 14
The uniform circular disk has a mass of 7.6 kg and
a radius of 0.6m The disk is suspended from a pin
at A and can rotate freely about A. The pin is
connected to a horizontal plate on smail wheels.
At the instant t = 0 a force is applied to the plate
(which is initially at rest), so that it accelerates
at a 1.5 m/s² (towards the right). Now
calculate the horizontal and vertical components
of the reaction at A and the magnitude of angular
acceleration of the plate at the instant t = Os.
