Hi all, I was just wondering:
suppose you have a setup of a torsion pendulum.
You have a disk and ring attached, and you want to calculate the moment of inertia of the system.
Do you just add the separate moment of inertia's of it?
Like it would be: 1/2 mR^2 + 1/2M_2 (R_1^2+R_2)^2 = I_net ??
My friend was discussing this with me today, and he got something different, and I am confused on it.
EDIT: actually i just found out how to do this. Please disregard (could a moderator please delete this post; i can't find the delete button)
