A cable is attached to a 1.40 kg block A, is looped over a fixed peg at C, and is attached to plate B.(Figure 1) The coefficient of static friction between the plate and the block is u4 = 0.150, the coefficient of static friction between the plate and the inclined plane is uR = 0.300, and the coefficient of static friction between the cable and the peg is uç = 7.00x10-2. If the plane's angle is 30.0 degrees, what is the maximum mass that plate B can have such that it does not slide down the plane? Express your answer numerically in kilograms to three significant figures. • View Available Hint(s) vec ? mB = kg
