The work input for a machine is the amount of energy or force that is put into the machine in order to make it operate. It is the energy that is required to do work on the machine and make it perform its intended function.
The energy that is used to make the machine work.
A machine's job is to make man's work easy !!
A device to make work easier is a machine, such as a lever.
a car is a machine that has a engine which work easy!

Effort force - Force applied to a machine when a machine is used to do work. A. Monjay Sutherland
Work done with a machine can make the task easier by reducing the amount of force or energy required. This means that the same amount of work can be achieved with less effort when using a machine compared to doing the work without one.
Make sure you make the right number of sacrifices

In an ideal scenario, the work done with a machine is the same as work done without a machine because the total work output must be equal to the total work input. While machines can make work easier by multiplying force or changing the direction of force, they cannot create energy. Therefore, the work done by the machine should ideally be equal to the work done without a machine.
simple machine such as pulleys and levers make work easier
