The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.
First Class LeverIt is a First class lever.
A third class lever is a lever where the force is applied between the fulcrum and the load. A fishing rod is a third class lever if it is fixed at the base and the hand holding the rod is between that fulcrum and the other end of the rod. It is also a third class lever by extension of your arm, wherein the fulcrum is your elbow and the force is your biceps or triceps muscle, which attaches close to that fulcrum.In a limiting case, a fishing rod is a first class lever if it is supported between the ends and you hold it at a point beyond that fixed fulcrum. This is not common, I think.
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.
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
Second class
1st class lever, with the axis of the elbow in the center of the force generated by the triceps proximally and the resistance of the hand and forearm distally
No. The racket is an extension to the arm, and the fulcrum is either the wrist or the elbow, with the force being the muscle and the load being the racket/badminton. This makes it a first class lever, unless you are swinging on an inside curl, not a normal swing, in which case it would be a third class lever. The difference is biceps (third class) versus triceps (first class).
