Two workers pull on the pole shown with forces and . a) If |F| = 140 N, || = 100 N, h = 9m, h = 4.5m, & 0 = 35, find the net moment about point A. If the pole is free to rotate about A, would it rotate clockwise or counterclockwise? b) If the worker pulling with force F adjusts the magnitude of the force such that there is no rotation, what is the reaction force at A? B hi h MA (Nm) = FA (N) =
