Question

diference between load and effort

Answer 1

Lever systems are simple machines that change or increase the input force that we apply to the load. The lever provides us with some mechanical advantage, which is defined as the degree to which the input force is increased. There are three parts associated with these simple machines, the load, the fulcrum, and the effort. All of these are placed at different points on the lever systems and the positioning of each determines the type of lever system.

The fulcrum is the pivot point on which the lever rests and pivots. A load is that object that we try to move or lift or simply an object on which output force acts. An effort is the input force that we apply to move or lift the load.

If the fulcrum is in between load and effort than the lever is of Class 1. For example, a see-saw.

If the load is in between fulcrum and effort than the lever is of Class 2. For example, a wheelbarrow.

If the effort is in between load and fulcrum than the lever is of Class 3. For example, a baseball bat.

Answer 2

Load is a term frequently used in engineering to mean the force exerted on a surface or body.
Effort is applied at one end of the bar and weight can be lifted from the other end.
