A homogeneous rod AB of mass m and length l leans with its lower end against the wall and is kept in the inclined positions by a string DC (Fig). The string is tied at point C to the wall and at point D to the rod so that `AD = AB//3`. The angles formed by the string and the rod with the wall are `alpha` and `beta` respectively. Find all possible values of the coefficient of friction `mu` between the rod and the wall. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/SSK_ATP_PHY_C01_E01_048_Q01.png" width="80%"
