A uniform circular disk, of 6-kg mass and 0.4-m radius, is placed at the corner, in contact with a vertical wall at A and a horizontal floor at B (Figure 6). A 100-N force is applied to the disk at the top point in the direction as shown in the figure. It is known that the coefficients of static friction between the disk and the wall and the floor are the same. question : Set up three equations of equilibrium at the critical state just about to move, in terms of thenormal forces (NA, NB) and the coefficient of static friction.
