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.

Is your arm a first class lever?
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
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.

Is humeral-ulna joint an example of second class lever?
No, the humeral-ulnar joint is not an example of a second-class lever. Second-class levers have the resistance located between the fulcrum and the effort, while the humeral-ulnar joint involves the motion of the arm from the elbow.
What class of levers describes the deltoid abducting the arm?
The deltoid abducting the arm is an example of a third-class lever, where the effort (muscle force) is applied between the fulcrum (shoulder joint) and the resistance (weight of the arm).
What kind of lever has a fulcrum resistance arm and effort arm?
A Class 2 lever has the fulcrum located at one end, with the resistance/load in the middle and the effort applied at the other end. The effort arm is shorter than the resistance arm in a Class 2 lever.
What does third class lever do?
A third-class lever is a type of lever where the effort is placed between the load and the fulcrum. This means that the effort arm is shorter than the load arm, resulting in a mechanical disadvantage. Third-class levers are commonly found in the human body, such as when using muscles to move limbs.
What class of lever is a football player's arm while he throws the football?
A football player's arm while throwing a football is an example of a third-class lever, where the effort is between the fulcrum (shoulder joint) and the resistance (football). The bicep muscle applies the effort to move the forearm, which propels the football forward.
What class lever is dumbbell front raises?
When raising dumbells in front of you by using only the forearm, the pivot is the elbow joint; the load is the dumbells at the opposite ends of the arm from the elbow joint; and the position of the effort is where the muscles of the arm are attached by tendons to the arm bones near the wrist. This is a third class lever system.
Is the arm a third class lever?
Yes, the arm is considered a third class lever because the effort (muscle force) is applied between the load (object being lifted) and the fulcrum (joint). This allows for greater range of motion but requires more effort to overcome the load.
