Full Answer

Machines can also reduce the amount of time it takes to perform an action by increasing the amount of force to an object. One example of a simple machine is a pair of pliers. When the two large ends of the pliers are squeezed together, the smaller ends come together to apply a greater force to cut through an object. This force is greater than an individual could pinch.
