The velocity ratio of a pulley system is defined as the ratio of the distance moved by the effort to the distance moved by the load. In this case, the effort moves a distance of 20m while the load moves a distance of 2m.
Velocity ratio = (Distance moved by effort) / (Distance moved by load)
Velocity ratio = 20m / 2m = 10.
So, the velocity ratio of the pulley system is 10.
In using a pulley system, an effort of 100N is needed to raise steadily a load of 800N through a distance of 20m and the load is then moved up a distance of 2m, calculate the velocity ratio
