Rotational Weight Calculator

Formula

The formula to calculate the rotational weight is:

\[ \text{RW} = m \times r \times a \]

Where:

RW is the rotational weight (N).
m is the mass (kg).
r is the radius (m).
a is the angular acceleration (rad/s^2).

What is Rotational Weight?

Rotational weight is the force required to rotate an object around an axis. It is calculated by multiplying the mass of the object, the radius from the axis of rotation, and the angular acceleration. This calculation is useful in various fields such as mechanical engineering and physics to understand the dynamics of rotating systems.

Example Calculation

Let's consider an example:

Mass (m): 5 kg
Radius (r): 2 m
Angular Acceleration (a): 3 rad/s^2

Using the formula to calculate the rotational weight:

\[ \text{RW} = 5 \times 2 \times 3 = 30 \text{ N} \]

This means that the rotational weight for this scenario is 30 N.
