The biceps is a class 3 lever
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.
No. A ramp is a ramp, one of several simple machines besides the lever.
An oar is a class 3 lever. This is because the oar, like all class 3 levers, is not used to reduce the force needed to move the load, but is used to increase the amount of travel of the load.

I do not believe a Bolt is classified as a lever as it does not have a fulcrum point. If it is, it would depend on what the bolt was being used for. If I had to guess, i would say class three
They are tools used to hold or grip things. - NOBODY who uses them seriously wonders what class of lever they are. (only teachers know important stuff like that )
Is it a third class
A stapler is designed in such a way that it can be used with power at the middle or work at the middle. Mostly it is used with power at the middle; in this case it is class 3. If the power is applied at the end it is class 2.
