Lever Arm Principle

They help us in lifting loads with lesser effort. The lever is one of the most basic forms of a machine.

Both the tired traveler and the experienced women reduce the lever arm which is the point of application of the force of gravity.

Lever arm principle. The force applied to make the object move. Levers are all around us and within us as the basic physical principles of the lever are what allow our tendons and muscles to move our limbs. A lever will have a point to apply the effort and it is termed as effort arm and similarly lever will also have a point for lifting the load which is termed as load arm.

Inside the body the bones act as the beams and joints act as the fulcrums. Point at which the lever is pivoted. Third class levers allow you to do fast movements such as throwing kick ing or swinging a tennis racket.

This hinge end or point will be termed as fulcrum. It consists of a beam or rigid rod pivoted at a fixed hinge or fulcrum. The object which we are lifting.

Lever will be free to rotate about this fulcrum. When you kick a ball you use the bones. Of the upper arm pulls the lever the lower arm upward.

The fulcrum or pivot point is the elbow and the weight or resistance is the weight of the lower arm and the weight that s held in the hand. It has been practically found that when two equal forces acting in opposite directions i e clockwise and counterclockwise are applied to a uniform lever. Principle of the lever it has been found by experiment that two equal forces acting in opposite directions i e clockwise and counterclockwise and applied to a uniform lever at equal distances from the fulcrum counteract each other and establish a state of equilibrium or balance in the lever.

Principle of the lever.
