COMPLEX MACHINE

A complex machine is made up of two or more simple machines that work

together to make a task easier. These machines often require external energy

sources like electricity, fuel or human force.

Examples of Complex Machine

Some examples of complex machine include:

Bicycle: A bicycle uses wheels (which work as a wheel and axle), pedals

(which act as levers) and gears and chain (which act as a pulley system) to
help it move. The brakes also act as levers to stop the bicycle.

Scissors: Scissors have two levers joined at a fulcrum (the point where they
meet). The blades act as wedges to cut things easily.
