What is a compound machine?

Answer 1

A compound machine is a machine made of two or more simple machines.

A compound machine also moves in more tha one movement.
Any combination of simple machines working together

a combination of 2 simple machines.. (simple machines include lever, inclined plane,wedge,screw,pulley,wheel and axle,)

examples of compound machines are bicycle fork knife and car..
compound machinemachine made up of a combination of two or more simple machines.
Compound machines are machines that consist of one or more simple machines (such as a screw and a pulley or a lever and a wedge).
A compound machine is a machine made out of two or more simple machines (such as a screw and a pulley or a lever and a wedge).
Machine - is a device that helps us do work (work is a force that acts on an object to make the object move. To get work, you multiply force by distance)

A simple machine - is a tool or device made up of one basic machine (there are 6 simple machines screw, ramp/inclined plane, wedge, pulley, wheel and axele, and levers.)

ex. of simple machines are: (screw - screw, hose nozzle, etc.) (inclined plane - slide, ramp etc. ) (wedge -chisel, knife, etc.) (pulley - crane, flagpole, etc.) (wheel and axle - door knob, steering wheel, bicycle wheel, etc.) (Lever - 1st class lever: see -saw, 2nd class leer: wheelbarrow, 3rd class Lever: hockey stick, broom, etc.)

a Complex Machine - is a system in which simple machines all work together, parts of a complex machine that have just one function are called subsystems and often contain a simple machine.

ex. of complex machines can be as simple as scissors, or as complicated as a lab top

A complex machine is really 2 or more simple machines in one machine

ex. Car or a bicycle
