it means when you are playing and your arm resists
The elbow is the resistance because it's the point that lifts are moves.

If a first class lever with a resistance arm measuring 2 feet and an effort arm measuring 8 feet are being used, what's the mechanical advantage
first class levers actually in front of the effort and resistance forces
No, the force is applied to the lever, but is not an example of a lever. A lever is made up of a fulcrum, a force/load, and a force arm.-there are three types of levers-1st Class-The fulcrum is between the force arm and the resistance arm.ex:Seesaws, crowbars, and oars.-2nd Class-The resistance is between the force arm and the fulcrum.ex: Wheelbarrows and nutcrackers.-3rd Class-The force is applied between the resistance and the fulcrum.ex: Brooms and a kicking leg.Hope this helps.a08Deevic88www.ETangerineE.webs.com
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
a lever
Divide the length of the force arm by the length of the resistance arm.
The class 3 lever always has a longer resistance arm than the force arm. This is because the distance from the Fulcrum to the load/resistance is always going to be further that the fulcrum to where the effort/force is applied. If you look at a diagram of a 3rd class lever, you will be able to see why this is.

a lever with an effort arm of 2 inches
increase the effort arm to 8 feet

the fulcrum, load and effort The three parts of a lever , fulcrum, resistance arm and effort arm, work together to make it possible to lift a weight using less force ...
