WebApr 25, 2024 · The third type of lever has the disadvantage of reducing the force exerted on the system. The force is between the load and the fulcrum. While it does create a mechanical advantage, it reduces the overall force, leading to inefficiency in the system. In the case of an arm, the bicep produces the force, and the elbow is the fulcrum. Precision 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.
