A block of mass is positioned underneath an overhang that makes an angle with the horizontal. You apply a horizontal force of on the block. Assume that the friction force between the block and the overhang is large enough to keep the block at rest. What are the normal and friction forces (call them and ) that the overhang exerts on the block? If the coefficient of static friction is , for what range of angles does the block in fact remain at rest?
