When a system oscillates angular long with respect to a fixed axis then its motion is called angular simple harmonic motion.
Conditions to Execute Angular SHM:
The restoring torque (or) Angular acceleration acting on the particle should always be proportional to the angular displacement of the particle and directed towards the equilibrium position.
Τ ∝ θ or α ∝ θ
Where,
- Τ – Torque
- α angular acceleration
- θ – angular displacement
