Each segment of each finger are individual 3rd class levers.
3rd Class Lever 3rd Class LeverTweezers are an example of a third class lever.
The human arm is an example of a 3rd Class lever when bent , but when u straighten it , it becomes a 1st Class lever ~
3rd class when the base is fixed to something (eg. boat or wharf). 1st class if the upper arm is rigid and lower is used to push

3rd class levers are in your arm.
Your arm is a really good example
It is a third class lever.
The three types of levers are the 1st class, the 2nd class, and the 3rd class
Each segment of each finger are individual 3rd class levers.
you have lots of lever in your house, like a light switch, or a mouse trap! it all depends on if you need 1st 2nd or 3rd class levers.

1st class levers are levers which have fulcrum between the load and effort.1st class lever in our body is our elbow joint .fulcrum:elboweffort:bicepsload:armarm and head
Levers can be all of them. A first class lever is when the pivot (funcrum) is in the middle. A second class lever has the load (resistance) in the middle, and the third class lever has the effort (force) in the middle. For example, a see-saw is a first class lever because the fulcrum is the in middle. A exmaple for a second class lever would be a can opener because the load, the can, is in the middle. And last, the thrid class lever is a arm because the effort is in the middle, because your elbow gives the effort to move the arm.
