A hammer is a 3rd class lever. A third class lever has a load-effort-fulcrum configuration. What is interesting about a hammer is that though the load is the head of the hammer, the effort and the fulcrum are both in the hand. What makes it a 3rd class lever is that the effort is more in the hand and fingers, while the fulcrum is closer to the base of the hand at the wrist.
Yes. A 3rd class lever has the fulcrum, in this case your elbow, on one end; the load, or nail, on the other; and the effort, where your hand moves the hammer, in the middle.
A second class lever has the load in the middle, such as a wheelbarrow.
A first class lever has the fulcrum, or pivot, in the middle.
Becuse the fulcrum is on the left (hammer) load is on the right (nail) and effort is in the middle and going upward.

A hammer pulling a nail would be first class ^^
yes it is
a first-class lever
A claw hammer
A nail clipper is a class two lever coupled to a class three lever.
The hammer is acting as a lever. The force exerted against the fulcrum (the head of the hammer) causes the claw end to lift and extract the nail.
A claw hammer is a pair of levers perpendicular to each other. When you exert force on the handle of the hammer, it transfers it's work to the second lever, or the head of the hammer. That then creates work at the claw, where you are pulling that nail with much greater force than you could exert without the hammer.
The hammer talked to the nail.
A claw hammer
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.
Depending on what you are using the hammer for. If the hammer is been used to pull up a nail then yes but if its been used to hammer in a nail then no. For something to be a lever it must have a fulcrum which the curve on the hammer works as as you try to pull out a nail.
A hammer is a lever because when you want to remove a nail it helps to pry it out of the place.
A claw hammer is a lever when it is being used to pull a nail out.
