How is torque calculated?

• A. by multiplying the speed by distance
• B. by adding the force and distance
• C. by multiplying the distance from the fulcrum and the force applied
• D. by calculating the area of the lever

Answer: (C)

Torque is a measure of the rotational force applied around a pivot point or fulcrum. The correct calculation method involves multiplying the distance from the fulcrum to the point where the force is applied (known as the lever arm) by the magnitude of the force. This relationship highlights that torque depends on both the amount of force and how far that force is applied from the pivot point. Mathematically, torque (τ) can be expressed as τ = r × F, where r is the distance from the fulcrum and F is the applied force. In practical terms, understanding how this calculation works is crucial in fields such as engineering and physics, as it affects performance-related tasks, such as tightening a bolt or turning a steering wheel. The effective use of torque can significantly determine the efficiency and safety of mechanical systems.
