mass of cabinet m = 30 kg
weight of cabinet mg = 30 x 9.8 N
coefficient of static friction = 
= 0.80
limiting frictional force = 
= 235.2
N
this is the maximum possible frictional force.
However when Bob is pulling the cabinet with a force 200 N (direction is horizontal), cabinet is not moving.
It is in equilibrium.
frictional force on the cabinet = 200 N

By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...
