Solution 4.86
A 120-lb cabinet is mounted on casters that can be locked to prevent their
rotation. The coefficient of static friction between the floor and each caster is
0.30. Assuming that the casters at both A and B are locked, determine (a) the
force P required to move the cabinet to the right, (b) the largest allowable
value of h if the cabinet is not to tip over.
