Question

A lever that always has a mechanical advantage of less than 1 has

• A. Load between effort and the fulcrum
• B. The effort between the load and the fulcrum
• C. Fulcrum between the load and effort
• D. Effort and load act at the same point

Answer 1

The correct option is B

The effort between the load and the fulcrum

Explanation

• In Lever of the Third Order, Effort acts in the middle.
• $MechanicalAdvantage=\frac{Effortarm}{Loadarm}$
• Mechanical Advantage is always less than one because the effort arm is always smaller than the load arm.

Hence the answer is The effort between the load and the fulcrum.
