A cable is attached to a 2.1 kg block A. Block A is looped over a fixed peg at C and is attached to plate B. The coefficient of static friction between the plate and the block is μa=0.30. The coefficient of static friction between the plate and the inclined plane is μb=0.35 and the coefficient of static friction between the cable and the peg is μc=0.41. If the plane’s angle is 30 degrees, what is the maximum mass that plate B can have such that it does not slide down the plane and remains stationary?

Question
A cable is attached to a 2.1 kg block A.
Block A is looped over a fixed peg at C and is attached to plate B.
The coefficient of static friction between the plate and the block is μa=0.30. The coefficient of static friction between the plate and the inclined plane is μb=0.35 and the coefficient of static friction between the cable and the peg is μc=0.41.
If the plane’s angle is 30 degrees, what is the maximum mass that plate B can have such that it does not slide down the plane and remains stationary?
