Fig.8.14: A movable pulley e. A load of 500 N is lifted to the height of 18 m by applying an inclined plane through the distance of 27 m . If the effort applied is 400 N, calculate the efficiency of the simple machine. If the same load is to be lifted to the same height by using effort of 300 N keeping the efficiency constant, calculate the length of the slope. [222.857 N].
