WebThe moment of intertia of the first point is i1 = 0 (as the distance from the axis is 0). Of the second point: i2 = m (L/2)^2 = mL^2/4. Of the third point: i3 = mL^2. The 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. 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. …
