🔄 How does a shaft twist under torque?

The torsion formula explains it:

👉 θ = TL / GJ

Where:
T = Torque applied
L = Length of shaft
G = Shear modulus (material property)
J = Polar moment of inertia

More torque or length → more twist
Stronger material or bigger section → less twist

This is how engineers design shafts in machines and vehicles!
