In physics and engineering, a moment is the product of a force and the perpendicular distance from the point of rotation to the line of action of the force. It represents the tendency of a force to rotate an object around a fixed axis. Moments are crucial in understanding rotational motion and are commonly used in structural engineering, mechanics, and physics.

The formula for calculating moment is:

\[ M = F \times d \]

Where:

- \(M\) is the moment, typically measured in Newton-meters (Nm) or foot-pounds (ft·lb)
- \(F\) is the applied force, measured in Newtons (N) or pounds-force (lbf)
- \(d\) is the perpendicular distance from the axis of rotation to the line of action of the force, measured in meters (m) or feet (ft)

Let's calculate the moment when a force of 50 N is applied at a distance of 2 m from the axis of rotation:

- Identify the known values:
- Force (F) = 50 N
- Distance (d) = 2 m

- Apply the moment formula: \[ M = F \times d \]
- Substitute the known values: \[ M = 50 \text{ N} \times 2 \text{ m} \]
- Perform the calculation: \[ M = 100 \text{ Nm} \]

Let's visualize the moment with our example:

This visual representation shows:

- The axis of rotation (red dot)
- The lever arm length (d = 2 m, green dashed line)
- The applied force (F = 50 N, red arrow)
- The resulting moment (M = 100 Nm, blue arc)

Understanding moments is essential in various applications, from simple machines like levers and pulleys to complex engineering structures and biomechanics. This calculator helps you quickly determine the moment, force, or lever arm length in various scenarios.
