Yes, the human hand can be considered an example of a lever. The bones of the hand act as the lever arm, the joints act as the fulcrum, and the muscles provide the force to move and manipulate objects. This allows for the hand to perform a wide range of movements and tasks.
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 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.
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
Scissors are an example of a class 1 lever, where the fulcrum is located between the input force (your hand) and the output force (the blades).
A hammer pulling a nail out is an example of a lever because the hammer acts as the lever, the nail acts as the fulcrum, and the force applied by our hand is the effort. When we apply force to the handle of the hammer, it creates a turning effect that lifts the nail from the surface, similar to how a lever functions.

No, a hand drill is not a lever.

An example for a double lever is pliers

Spanner is not a class 2 lever. A class 2 lever has the load between the fulcrum and the effort, like a wheelbarrow. A spanner is a type of hand tool used to provide grip and mechanical advantage in turning objects such as nuts and bolts.
First Class LeverIt is a First class lever.
Yes, a broom is an example of a second-class lever. In a second-class lever, the load is located between the fulcrum and the effort. When you push down on the handle of a broom to sweep, the load (dirt and debris) is located in between the fulcrum (floor) and the effort (your hand on the handle).
