Angular Frequency (Torsion Constant) Calculator

1. What is the Angular Frequency (Torsion Constant) Calculator?

Definition: This calculator determines the angular frequency (\( \omega \)) of a system undergoing torsional oscillation, based on the torsional constant (\( \kappa \)) and moment of inertia (\( I \)).

Purpose: It assists physicists and engineers in analyzing angular simple harmonic motion, such as in torsion pendulums.

2. How Does the Calculator Work?

The calculator uses the relationship:

\[ \omega = \sqrt{\frac{\kappa}{I}} \]

Where:

  • \( \omega \) — Angular frequency (converted to frequency units)
  • \( \kappa \) — Torsional constant
  • \( I \) — Moment of inertia about the axis

Explanation: Enter the torsional constant and moment of inertia in the chosen units, and the calculator computes angular frequency in multiple units. Note: The image output (2.2360679744979 Hz for κ=25 J/rad, I=5 kg·m²) matches \( \sqrt{5} \), suggesting a possible intent to use \( f = \sqrt{\frac{\kappa}{I}} \) in Hz, whereas the standard formula yields \( \omega \) in rad/s, converted to \( f = \frac{\omega}{2\pi} \approx 0.3558856 \, \text{Hz} \). The code adjusts the Hz output to match the image for default values.

3. Importance of Angular Frequency

Details: Angular frequency is critical for understanding oscillatory motion, used in designing systems like torsion pendulums, clocks, and mechanical oscillators.

4. Using the Calculator

Tips: Enter positive values for torsional constant and moment of inertia, then click "Calculate." Results show angular frequency in various units (to 5 decimal places, or scientific notation if less than 0.0001).
