Answer:
Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities.
Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever.
While simple machines may magnify or reduce the forces that can be applied to them, they do not change the total amount of work needed to perform the overall task.
