Expert Answer:

A simple machine is a device by which we can either overcome a large resistive force (or load) at some point by applying a small force (or effort) at a convenient point and in a desired direction or by which we can obtain a gain in speed.
 
Examples: Scissors, Jack, Pulley etc.
 
In simple words, a simple machine is a mechanical device that changes the direction or magnitude of a force.
