The angle of repose:- it is the minimum angle that an inclined plane makes with the horizontal when a body placed on it just begins to slide down. let any inclined plane inclined with Īø angle with horizontal and a body which mass is m just begins to slide down. then, mg.sinĪø =Ī¼N where Ī¼ is the coefficient of friction and N is the normal reaction. N = mg.cosĪø now, mg.sinĪø =Ī¼mg.cosĪø …
