When a force is applied to the large drum, the rope on the small drum winds onto D and off of d. A measure of the force amplification available with the pulley-and-rope system is the velocity ratio, or the ratio of the velocity at which the force is applied to the rope (VF) to the velocity at which the weight is raised (VW). A snow shovel is an example of this simple machine. An Investigation And Guide. The mechanical benefit of this tilted plane came in 1586 from the Flemish engineer Simon Stevin and put in the other simple machines.
