POWER SOURCESMachines get their power from different sources.

Some machines work on manual power. For example: a bike, a spade…

Some machines run on electricity. For example: traffic lights, mobiles phones…

Others get their power by burning fuel. For example: cars

COMPLEX MACHINES AND THEIR USES

The majority of machines we use in our lives are complex.

Most of the time, complex machines are formed by using different types of simple machines.

http://www.google.es/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0CAcQjRw&url=http://portal.teemss2.concord.org/content/fourier/trial_id_56_invid_22.html&ei=mNNhVdadCcarU6mfgbAK&psig=AFQjCNEx4Fy2VKm-4GUusA6KHwMZuysU4w&ust=1432560877589962

Brakes are a set of levers.

The handlebar is a lever.

The wheels turn on an axle.

Pedals are levers that use human force to move a cyclic gear.

USING MACHINES

We need to be careful when we use machines.

To avoid hurting ourselves, we must always read the safety instructions.

Many machines that need fuel to work, produce pollution. We must reduce the use of those machines.
