Mechanism are designed to perform tasks. The basic principle behind mechanism is to
- Transform energy when a force is applied over a certain distance to do work.
Mechanism helps us to gain
- Greater output distance moved with smaller input distance moved
- Greater output force produced with small input force
- Greater output Speed of movement with slower input speed of movement.
