Get this resource at a discount in our Musculoskeletal System Unit! Different classes of levers are identified by the way the joint and muscles attached to the bone are arranged. Slideshow: Types of Bone Fractures, Healing, & Interventions (Explain). Although one of the six simple machines is not superior to another, each machine offers its own distinct advantages for various engineering applications. The load arm (LA) is the distance between the fulcrum and the load; in the body, this is the distance between the joint and the loaded body part. The forearm length measurement includes zeros behind the decimal that would be unnecessary for a definition, so they suggest a level of in a measurement.
