A man uses the inclined plane to lift a 50kg load through a vertical line height of 4.0m. The inclined plane makes an angle of 300 with the horizontal. If the efficiency of the inclined plane is 80%, determine.
(a) The effort needed to move the load up the inclined plane at a constant velocity.
(b) The work done against friction in raising the load through the height of 4.0m. (Take g = 10N/kg).
