In aircraft design and engineering, a moment refers to the turning effect or torque produced by a force acting at a distance from a reference point. Moments play a critical role in maintaining the balance and stability of an aircraft. Here’s the formula, definition, and SI unit for moment:
Moment Formula: The formula for calculating a moment is:
- Moment (M) is the turning effect or torque, measured in Newton-meters (Nm) in the international metric system or pound-feet (lb-ft) in the imperial system.
- Force (F) represents the force applied, measured in Newtons (N) in the metric system or pounds-force (lbf) in the imperial system.
- Distance (d) is the perpendicular distance from the point where the force is applied to the reference point (or axis of rotation), measured in meters (m) in the metric system or feet (ft) in the imperial system.
