On the basis of a given load of pulley Fg = 4000N, Determine the load of the bearing rope BA. The load should be the basis for the design of the supporting ropes, pulleys and ropes to mount joints A and B. Basically you need to evaluate the moments and need the reactions in the supports, these are somehow lattices. I need FA and FB and FC , and what is FBA?
