1. The homogeneous rectangular block of mass m rests on the inclined plane which is hinged about a horizontal axis through O. If the coefficient of static friction between the block and the plane is µ,, specify the conditions which determine whether the block tips before it slips or slips before it tips as the angle () is gradually increased.
