What is defined as the ratio of the output force produced by a machine to the input force applied?

• A. Efficiency
• B. Mechanical Advantage
• C. Force Ratio
• D. Work Done

Answer: (B)

The concept described in the question pertains to mechanical advantage, a fundamental principle in physics related to machines and forces. Mechanical advantage is defined as the ratio of the output force produced by a machine to the input force applied. This ratio indicates how effectively a machine amplifies an input force, allowing a user to lift heavier loads or perform work with less input effort. When the mechanical advantage is greater than one, it means that the machine is able to produce more output force than the input force that is applied, demonstrating its effectiveness in reducing the effort needed for a task. This concept is vital in understanding the efficiency and functionality of various machines, such as levers, pulleys, and gears. In contrast, efficiency relates to the ratio of useful work output to total work input, and work done refers to the energy transferred when a force is applied over a distance. Force ratio is not a standard term used in physics to describe these concepts. Thus, identifying mechanical advantage as the answer correctly aligns with the definition provided in the question.
