Document Summary

Slide 2: cells of muscles are part of a functional level system. A biological example is standing up on your tip-toes or jumping. Biologically, third class levers are the most common, example a bicep muscle. Slide 3: mechanical advantage is defined mathematically as the length of the effort arm divided by the length of the load arm, the effort arm is the length of the fulcrum to the effort. The load arm is the length of the fulcrum to the load. If you know the lengths of these 2 arms you can calculate mechanical advantage, which tells us how efficiently muscular force (effort being exerted) is translated into leverage, in other words how effectively it"s used to lift that load. In third class levers, the load arm is much greater than the effort arm. So in these third class levers, which are common in biological systems, have very low mechanical advantage but they have the advantage of being speed levers.
