Wheelbarrows and nutcrackers are known as second-class levers. This is because their resistance is between the force arm and the fulcrum.
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
Your arm can be considered a first class lever.
The biceps brachii acts as a class 3 lever to flex the arm. The deltoid also acts as a class 3 lever to abduct the arm, as does the teres major in adducting the arm. The triceps brachii, however, acts as a class 1 lever to extend the arm. In other words, when you're bending your arm or swinging it toward your body or away from your body, it's a class 3 lever. But if your arm is bent and you're straightening it, then your arm is a class 1 lever.
In third class levers effort P is in between the fulcrum F and the load W. According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
