The names of the types of levers are class 1, class 2, and class 3. For a class one lever the fulcrum lies between the force arm and the lever arm. The teeter totter is a classic example of this type of lever. First class levers include: a claw hammer, a water pump, balance, a crowbar, a car jack, pliers and scissors.

Is a claw hammer a simple machine?

A hammer is a lever, one of the six types of simple machines. A lever is defined as any rigid bar that pivots around a fixed point, called a fulcrum, to apply force. A claw hammer can have two possible fulcrums, depending on how it is used. When driving a nail, the fulcrum is wherever the user holds the handle.

Where is the fulcrum on a nail puller?

When driving a nail, the fulcrum is wherever the user holds the handle. If using the hammer to pull the nail back out again, the fulcrum becomes the point where the top of the hammer rests against the surface holding the nail. Other common household levers include crowbars, hoes, scissors and bottle openers.
