Answer:
L = 0.5*M*R^2 * w
Step-by-step explanation:
Solution:-
- The angular Momentum (L) of a rigid body about any axis is given by the following relationship:
L = I*w
Where,
I : Moment of inertia of the rigid body
w: The angular speed of the rigid body.
- The moment of inertia (I) for a disc is given by:
I = I_disc
I = 0.5*M*R^2
Where,
M : Mass of the disc
R : The radius of the disc.
- Hence, the Angular momentum (L) of the disc rotating about an axle is:
L = 0.5*M*R^2 * w
