Question

The weight of the wardrobe is W = 392.4 N with center of gravity at G. If the static friction coefficient between the wardrobe and the inclined surface is $\mu_s$ = 0.2 and a horizontal force P applied on it as shown in the figure above, where d = 0.8 m, l = 1.8 m, b = 1 m, h = 1.2 m and $\beta$ = 20°, then: (a) The magnitude of the force P for impending slip up is (N): (b) The magnitude of the normal reaction is (N): (c) The friction force is (N): (d) The position of the reaction measured from A is (N): (e) The magnitude of the force P for impending slip down is (N): (f) In case (e) above, the position of the reaction measured from A is (N):
