my results are that simple machines work by using force and some work.
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
