Simple machines include inclined planes, levers, wheel and axle, pulleys, and screws. It is important to remember that all machines are limited in their efficiency. No machine is 100 percent efficient in its efforts, so the mechanical advantaged gained must be considered worthwhile of the extra energy that will be required to accomplish the job.
