What is a 3rd degree lever?

A third-class lever is another example of a simple machine comprising a beam placed upon a fulcrum. In third-class levers, the fulcrum remains at one end of the beam—however, the force of the effort is now located between the fulcrum and the force of the load.

Is a tennis racket a lever?

Demonstrate how it is a class 3 lever, with the length of the equipment being the lever arm, the hand gripping at the end is the fulcrum and the other hand (most sports) or the index finger of the fulcrum hand (tennis racquet) produces the force of the swing (the “force in” on the image, or the “effort”).

What are the 3 levers in the body?

There are three types of lever.

  • First class lever – the fulcrum is in the middle of the effort and the load.
  • Second class lever – the load is in the middle between the fulcrum and the effort.
  • Third class lever – the effort is in the middle between the fulcrum and the load.

Why is broom a third class lever?

In a broom stick, the handle of the broom at the top is the fulcrum, we push the handle from somewhere in the middle, that is the input effort and the bristles at the end of the broomstick sweep dust from the floor, that is the output load. Therefore, a broomstick is a lever of class 3.

The advantage of a third-class lever is that the output force is applied over a greater distance than the input force. The output end of the lever must move faster than the input end in order to cover the greater distance.

How can you tell if a lever is a force multiplier?

Levers, such as this one, make use of moments to act as a force multiplier. They allow a larger force to act upon the load than is supplied by the effort, so it is easier to move large or heavy objects. The longer the lever, and the further the effort acts from the pivot, the greater the force on the load will be.
