Law of Inertia: A body will remain in its current state of motion (or stationary), until and unless, a net force is applied to it that changes its state 2. Law of Acceleration: An external force will cause the body to accelerate in direct proportion to the magnitude of force and in the same direction as the force ...

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.
