WebWhat is the mechanical advantage of the lever 2? class 2 lever mechanical advantage In class 2 lever the load situates between fulcrum and effort. As a result effort arm length is always more than load arm length for second class lever (class 2 lever). Hence, in case of class 2 lever the mechanical advantage value is always more than 1. Web3rd class levers are the most common levers, why? Although we use 3rd class levers more than any others in the human body, they in fact offer no mechanical advantage thus, regardless of where you apply the force, the force you apply must always be greater than the force of the load. thermometer wasserfest
