Extracted text: 4) The block A has a weight of WA and it is rested in the inclined plane with friction. Block A is being held in equilibrium with the help of block B which has a weight of WB-20 kN and is attached to the pulleys G, and G2. Both pulleys are with friction. All the friction coefficients are shown in the figure given below. To keep the system in equilibrium for avoiding the motion, what should be the weight of WA? (The possible direction of the motion is shown in the figure) 4 = 0.2 QG H, = 0.3 G, B. 4= 0.5 30 W= 20 kN
