1. WHAT IS A MECHANISM?

The moving parts of a bicycle are examples of everyday mechanisms that make the lifes (our lifes) easier and funnier.

These mechanisms make work easier because they transmit and trasform force and motion.Mechanisms transmit motion and force to receptors that make the work.This is the output force and motion.

All these mechanism require an input force, mechanisms transmit motion and force to receptors and finally perform the work.
