A complex machine is any machine made up of two or added simple machines. A simple machine is an elementary machine for making work easier. They modify or transmit force or motion. In a simple machine there is the wheel and the axle, the wedge and the jackscrew.

Simple machines, like ramps and levers, are simple. They have´t got many parts. Complex machines, like clock, are complex. They have got lots of parts.
SIMPLE AND COMPLEX MACHINES

A mechanism is a combination of moving parts that perform a specific action.

The gears are metal wheels with special theeth that fit together.

Gears have got many types of gears, I put something.

A chair of a bicycle is a support that helps you to pedal better and not get tired so fast.

The brake levers are connected to cables. These cables transmit the movement of the levers to the brakes on the wheels.
THE BRAKE LEVERS

The handlebar is a lever that changes the direction of the front wheel.
THE HANDLEBAR

The pedals are levers that turn a special wheel with gears, called a crank.
THE PEDALS
