The elevation of the platform is controlled by two identical mechanisms, only one of which is shown. A load of 1200 lb is applied to the mechanism shown. Knowing that the pin at C can transmit only a horizontal force, determine (a) the force in link BE, (b) the components of the force exerted by the hydraulic cylinder on pin H.
