Question

What is torsional equation?

Answer 1

1. The torsion equation or torsion constant is defined as the geometrical property of a bar’s cross-section that is involved in the axis of the bar.
2. It has a relationship between the angle of twist and applied torque whose SI unit is m⁴.
3. The torsion equation is given as follows:

$\theta =\frac{TL}{GJ}$

Where,
- $\theta$ is the angle of twist in radians.
- $T$ is the torque applied to the object.
- $L$ is the length of the beam.
- $G$ is the material's modulus of rigidity which is also known as shear modulus.
- $J$ is the Torsional constant.
