WebBy the theorem of perpendicular axes, I z=I x+I y. Now, x and y axes are along two diameters of the disc, and by symmetry the moment of inertia of the disc is the same about any diameter. Hence. I x=I y. and I z=2I x. But I z=MR 2/2. So finally, I x=I z/2=MR 2/4. Thus the moment of inertia of a disc about any of its diameter is MR 2/4. Web1Q10.30 - Moments of Inertia - Hoops and Disks.

WebThe total moment of inertia is just their sum (as we could see in the video): I = i1 + i2 + i3 = 0 + mL^2/4 + mL^2 = 5mL^2/4 = 5ML^2/12. The result is clearly different, and shows you cannot just consider the mass of an object to be concentrated in one point (like you did when you averaged the distance). WebMoment of inertia is the property of the body due to which it resists angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation. …
