A uniform rod is made to lean between a rough vertical wall and the ground. The coefficient of friction between the rod and the ground is mu_(1) and between the rod and the wall is mu_(2) . Find the angle at which the rod can he leaned without slipping.

In the diagram shown, friction is present only between therod and the wall. The mass of the rod is M and tht of the wedge is 3M. What is the minimum value of the coefficient of friction between the rod and the wall so that rod remains in the state of rest?

A horizontal uniform rod of mass 'm' has its left end hinged to the fixed incline plane, while its right end rrests on the top of a uniform cylinder of mass 'm' which in turn is at rest on the fixed inclined plane as shown. The coefficient of friction between the cylinder and rod, and between the cylinder and inclined plane, is sufficient to keep the cylinder at rest. The ratio of magnitude of frictional force on the cylinder due to the rod and the magnitude of frictional force on the cylinder due to the inclined plane is :
