Moment of Inertia of a Ring: Formula and Application

AI Thread Summary
The discussion focuses on finding the moment of inertia formula for a ring defined by its inner radius (R), height (h), and thickness (t). Participants clarify that the moment of inertia can be calculated by subtracting the moment of inertia of a disc with radius R from that of a disc with radius R + h. There is an emphasis on the importance of showing work or previous attempts to solve the problem. The community encourages collaborative problem-solving and sharing of insights. Overall, the thread highlights the formula's application in physics and the need for clear communication in seeking help.

Moment of Inertia

Hello community members,

Can anyone let me know, the moment of Inertia formula (I) for a ring with inner radius (R) and height (h). Thickness can be considered (t).

Awating response...

Hi getneotome! Welcome to PF! :smile:

Do you mean a ring with inner radius R and outer radius R + h?

If so, just remember that Moment of Inertia is always additive, so you can just subtract the Moment of Inertia of a disc of radius R from the Moment of Inertia of a disc of radius R + h. :smile:
 
Dear Community memebers,

Can anyone tell me the formula for Moment of Inertai (I) for a ring with inner radius of (R) and height (h) and thickness (t).

Awaiting response...

Kind regards..
 
Hi getneotome!

Thanks for the PM, but the idea is that you show us what you've done. :smile:
 
getneotome is this a problem you have to solve, or a result that you need for a problem that you have to solve?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
