First, second, and third class levers.
An example of a first-class lever is the joint between the skull and the atlas vertebrae of the spine: the spine is the fulcrum across which muscles lift the head.
An example in the human body of a second-class lever is the Achilles
tendon, pushing or pulling across the heel of the foot.
An example of a third-class lever in the human body is the elbow joint: when lifting a book, the elbow joint is the fulcrum across which the biceps muscle performs the work.

The load the fulcrom and the effort
Is a force an example of a lever?
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
