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.

SIMPLE AND COMPLEX MACHINES

EXAMPLES OF SIMPLE MACHINES

EXAMPLES OF COMPLEX MACHINES

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

MECHANISM

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

THE GEARS

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

TYPES OF GEARS

NOW, YOU ARE GOING TO SEE A

ONE EXAMPLE OF COMPLEX MACHINES

(BICYCLE) AND THEIR PARTS.

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

THE CHAIR

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

SIMPLE AND COMPLEX MACHINES.
