Answer 2

Answer:

A lever is a bar that turns on an unmoving point called fulcrum . When you push or pull on one end of the bar that pressure is called force. The object that is lifted on the other end is called the load .

There are three parts :

. Input force : (also called the effort) the force applied to the lever

.Output force (also called the load) - the force applied by the lever to move the load.
