Velocity- ratio of pulley -system having a mechanical-advantage less than the 2
Explanation:
- Ratio of Mechanical -advantage & Velocity- ratio give efficiency of the pulley-system
- It is find out that Mechanical advantage value is always become less than the velocity-ratio because of the friction or weight of the moving parts While Velocity- ratio remain constant irrespective of the friction.
- Mechanical-advantage is ratio of weight of load and force applied
- Velocity-ratio is ratio between distance measure by effort and by load
