There are three classes of levers and each represents a positional configuration of the fulcrum, the load and the force on the lever: Class 1: The fulcrum is located between …the applied force and the load Class 2: The load is situated between the fulcrum and the force Class 3: The force is applied between the fulcrum and the load No its a second class lever because the fulcrum is located at one end and the force is applied to the lever arm at the other end. The "load" in this case is the can.
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 trice…ps 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.
yes a pair of chopsticks is a first class lever...suck it ben
Second 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 ~
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 tha…n load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
the fulcrum lies between the effort and load the effort or force and makes it possible to perform the work
Arm is the example of 2nd class lever.
first class levers have fulcrum at center and load and effort at extremes, examples are seesaw and scissor.
In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors. In second class lever fulcrum is at one end and effort is at other …end. The load is at the middle. eg nutcracker.
A first class lever takes place when the fulcrum is between the force and load. This is possible by lifting the pole and balancing it with your hand. A second class lever take…s place when the load is between the force and the fulcrum. This is possible by lifting one end of the pole while the other end is touching the ground.
level 3 no yes no yes no es no yes
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
scissors are first class lever because they have fulcrum in between load and effort.
yes the arm is a third class lever
