WebL = mr 2 ω. But mr 2 term is thebody’s moment of inertia (I). L = I ω. We have learned that the torque induced on the body is the rate of angular momentum change . τ = dL/dt. Substituting angular momentum formula , τ = dIω/dt. τ = Idω/dt. The term dω/dt is the angular acceleration α of the body. i.e., α= dω/dt. WebClick here👆to get an answer to your question ️ The angular speed of a body changes from ω1 to ω2 without applying a torque but due to change in its moment of inertia.the ratio of radii of gyration in the two cases is dsdjjWebThe 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). dsd kranj

"Web11 apr. 2014 · Using the rotational acceleration of just the disk, the disk's moment of inertia was found to be .000163kgm2. The disk's geometric moment of inertia was .000138kgm2. This yielded a percent difference of 16.6%. The percent differences may have been caused by friction in the pulley or rotational motion sensor. " - Moment of inertia of all bodies
