## Question

###### 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 $B E,(b)$ the components of the force exerted by the hydraulic cylinder on pin $H$.
