The position of the spindle DE of a lift truck is partially controlled by two identical linkage-and-hydraulic-cylinder systems, only one of which is shown. A 3000-lb spool of electric cable is held by the spindle in the position shown. Knowing that the load supported by the one system shown is 1500 lb, determine
(a) The force exerted by the hydraulic cylinder on point G,
(b) The components of the force exerted on member BCF at point C.
