Question

The correct relationship between the velocity ratio ( V.R.), distance moved by load (dL) and distance moved by effort ( dE) is :

Answer 1

Velocity-ratio

Explanation:

• Velocity-ratio is that ratio which exist between distance moved or measured by effort to load.

• Mechanical-advantage is that ratio which exist between the output force to the input force.

• Efficiency is the ratio between mechanical-advantage to the velocity-ratio then multiplied by 100 ,we can get efficiency of mechanical -system.

• In the ideal condition of system, Numerical value of mechanical-advantage is equal to the velocity-ratio so efficiency become 100% but no system is ideal due to loss in system.
