Part A What is the magnitude of F for the system to remain in equilibrium? Two pulleys are attached to a shaft supported by the bearings at ends A and D. A downward 6-kN force is applied at the left-hand side of the pulley at B, and a downward 4-kN force is applied at the right-hand side. A horizontal (to the right) 9-kN force is applied at the top of the pulley at C, and the horizontal force F (to the right) is applied at the bottom. The pulleys at B and C have radius 150 mm and 100 mm, respectively. What is the magnitude of for the system to remain in equilibrium?
