Consider a solid rod of mass m and uniform density resting against a vertical wall and horizontal floor as shown in the figure. The coefficients of friction of the rod with the wall and with the floor are given to be ₁ and ₂ respectively. Gravity is acting downwards with acceleration due to gravity g . What should be the value of the inclination angle so that the rod stays in equilibrium?
