What does the moment of inertia depend on?

AI Thread Summary
The moment of inertia depends on several key factors: the mass of the object, its shape, and the location of the axis of rotation. The distribution of mass is crucial, as it affects how the moment of inertia is calculated. Angular velocity is not a factor in determining moment of inertia; rather, it is a variable that influences angular acceleration. The moment of inertia is defined as the resistance to changes in angular acceleration. Understanding these dependencies is essential for analyzing rotational dynamics.

What does the moment of inertia depend on?

-Angular velocity
-Shape of the object
-Location of axis of rotation
-Mass

Well, I think the location of the axis of rotation matters because it sets a reference point. I'm not sure about the others. Doesn't it also depend on how the mass of the object is distributed? So would that be the mass or shape of the object, or both? Also, moment of inertia was defined to be the resistance to the change of angular acceleration. But does that mean that it's dependent on the angular velocity?

Am I missing anything from above or incorrectly included any?

Look up the definition of moment of inertia, it will provide you a direct answer instantly.
 
yes if i remember correctly they are all factors of the moment of inertia except for the angular velocity which is a variable
 
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'
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...
