8: A two stage telescopic cylinder is used to tilt the body of a lorry. When the lorry is fully laden, the cylinder has to exert a force equivalent to 40KN at all points in its stroke. The outside diameters of the tubes forming two stages are 75mm and 100mm. If the pump powering the cylinder delivers 12 l/min, calculate the extend speed and pressure required for each stage of the cylinder when tilting fully laden lorry.
