Answer 1

Answer:

A device that does work with only one movement and changes the size or direction of a force is a simple machine.

Explanation:

• For applying force, any used basic mechanical devices are simple machines.
• Simple machine changes the direction as well as the amplitude of the applied force i.e. we can increase or decrease the magnitude of the force.
• A simple machine is the most basic mechanism to use the force as we need in big mechanical machines.
• Some of the examples of simple machines are inclined plane, lever, wedge, wheel and axle, pulley, and screw.
