What is a mechanism ? Mechanisms are devices that have been designed to make jobs easier.
They all have certain things in common:
They involve some kind of motion.
They involve some kind of force.
They must have some kind of input to make them work.
They produce some kind of output.
If we connect mechanisms together we can build mechanical systems called machines.
Example is this mechanical dog :)
