Question
A machine works as a
- force multiplier,
- speed multiplier.
In each case, state whether the velocity ratio is more than or less than 1.
Solution
- For a machine working as a force multiplier, displacement of load is less than displacement of effort. Thus, the velocity ratio is greater than 1.
- For a machine working as a speed multiplier, displacement of load is greater than displacement of effort. Thus, the velocity ratio is less than 1.
