COMPLEX MACHINES

Page 2: 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.

COMPLEX MACHINES

Page 3: 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.

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

MECHANISM

Page 7: COMPLEX MACHINES

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

THE GEARS

Page 8: COMPLEX MACHINES

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

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

What is complex machines? A complex machines is a any machines

made up of two or added simple machines. What is a mechanism? A mechanism is a combination of moving

parts that perform a specific action. What is break levers? The brake levers are connected to cables. What is pedals? The pedals are levers that turn a special

wheel with gears, called a crank.
