A device that makes work easier by reducing effort required increasing distance, or changing the direction of  the force.

The human race is always trying to find ways of making work easier. Machines are devices that make work easier. The principle involves lessening the effort required to lift or move a load or changing the direction in which the force is applied to a more convenient one. Levers and pulley systems help to move loads using by reducing the effort required. Mechanical advantage is the ratio of the load to the effort. A large mechanical advantage indicates that a much smaller effort is required to lift a heavier load.  Friction affects the way machines work and their efficiency. Pumps use the concept of pressure  to move fluid substance and act as machines.
