In third class levers effort P is in between the fulcrum F and the load W.
According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load.
Example:- forearm used for lifting a load on the palm.

EzraThe arm functions as a third-class lever when the effort is applied at the hand to lift a weight in the middle. The bicep muscle applies the force (effort) near the elbow joint (fulcrum) to lift an object (load) held in the hand. This lever configuration allows for a greater range of motion but requires more force to move the load.

Is your arm a first class lever?
Yes, the human arm is a third class lever. The biceps and triceps act as the effort and the load, with the elbow joint acting as the fulcrum.
What class of lever is your arm?
The human arm is primarily a third-class lever. The effort (force) is generated by the muscles in the arm, the fulcrum is the elbow joint, and the load (resistance) is the object being lifted or moved by the hand.
The human arm is example of which class of lever?
The human arm is an example of a third-class lever. In this type of lever system, the effort force is between the fulcrum and the resistance force. The bicep muscle provides the effort force, the elbow joint acts as the fulcrum, and the object being lifted is the resistance force.
What class lever is your arm?
Arm is the example of 2nd class lever.
Is an arm a first class lever?
Yes, an arm can be considered a first-class lever when the force is applied at one end, the fulcrum is in the middle, and the weight is at the other end. For example, when lifting a load with your forearm acting as the lever, the elbow serves as the fulcrum.
