Determine the M. I of horizontal axis XX passing through top of the semi-circle.

14 a) A body weighing 1000N rests on an inclined plane and is subjected to a horizontal (6)

force so as to keep it in equilibrium. If the angle of the plane is 30° and the angle

of limiting friction is 107,8൩0 the least and greatest value of the force to keep the
body in equilibrium.
