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.
Mechanical advantages allows humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy. Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.
Similarly, what are the characteristics of a simple machine? While simple machines take many shapes, they come in six basic types:
Wedge: A device that forces things apart.
Wheel and axle: Used to reduce friction.
Lever: Moves around a pivot point to increase or decrease mechanical advantage.
Inclined plane: Raises objects by moving up a slope.
Subsequently, one may also ask, how does simple machine make work easier?
Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That's because a machine doesn't change the amount of work and work equals force times distance
