    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.

                                                                                        Brake handle
                                                                                           (Lever)

                                                          Inclined
                                                           Plane

                                                            Pedal
                                                           (Lever)
                                           Gears and Chain                                Wheel
                                       (Pulley, Wheel and Axle)                     (Wheel and Axle)

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

                                                                                            Wedge

                                                                        Fulcrum

                                              Lever

                                                                                 Simple and Complex Machines
                                                                                                                        11
