COMPLEX MACHINES

COMPLEX MACHINES

Complex machines

A complex machine is a machine that is made up of many operating parts. 

  • Cars and bicycles are examples of complex machines

A bicycle has wheels and axles that move the bike along. The handlebars, handbrakes and brake pedals are all types of levers. Many bikes also have gears that allow the rider to change the turning force. You can change the gears to make it easier to ride a bike up an inclined plane. The pedals need to be turned more but it is easier to travel uphill.
