COMPLEX MACHINES

COMPLEX MACHINES � 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. � CHAIN � BACK WHEEL � BRAKE LEVERS � HANDLEBAR � PEDALS

SIMPLE AND COMPLEX MACHINES � 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.

NOW, YOU ARE GOING TO SEE A ONE EXAMPLE OF COMPLEX MACHINES (BICYCLE) AND THEIR PARTS.

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

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

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

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