# Angular Torque Calculator

An angular torque calculator is a vital tool for anyone involved in physics or engineering, as it helps in determining the torque produced by a rotating object. Torque, a measure of rotational force, is essential in various applications, from mechanical engineering to physics experiments. This calculator simplifies the process by allowing users to input mass, radius, and angular acceleration to obtain the angular torque value effortlessly.

## Formula

The formula for calculating angular torque (Ta) is given by:

Ta = m * r² * α

where:

- Ta is the angular torque,
- m is the mass,
- r is the radius, and
- α is the angular acceleration.

## How to Use

Using the angular torque calculator is straightforward:

- Enter the mass (in kilograms) of the object.
- Input the radius (in meters) at which the mass is applied.
- Specify the angular acceleration (in radians per second squared).
- Click the “Calculate” button to obtain the angular torque.

## Example

Suppose you have a mass of 5 kg, a radius of 0.3 meters, and an angular acceleration of 2 rad/s². By inputting these values into the calculator, you would compute the angular torque as follows:

Ta = 5 * (0.3)² * 2 = 0.90 Nm.

When you input this into the calculator, it should display 0.90 Nm as the result.

## FAQs
