The hook is subjected to three forces A and C as shown. (CE Board May 2012) A=35 kN 60 B=45 kN a. If the resultant of forces is 80kN and is acting along the positive x-axis, find the angle a. b. If a=60', what is the value of force C such that the resultant of forces A, B, and C acts along the x-axis? c. For the forces A, B, and C to be in equilibrium, what is the magnitude of the resulting force C?
