Deriving moment of inertia
The moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the … WebI know how to find the period of a physical pendulum. I also know the parallel axis theorem for moment of inertia. The part I'm struggling with is finding the moment of inertia about the center of mass of the square. In the video, he just uses the textbook derivation formula. I want to figure out how the formula is derived in the first place.

WebTo get an idea the moment of inertia of an annular disk is given by the equation, I=1 ⁄2M (R2²+R1²) Where, M denotes the annular disk’s mass. R1 denoted the annular disk’s inner radius. And R2 denotes the annular disk’s outer radius. In this article, we are going to learn how to derive the moment of inertia formula of an annular disk. 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.
WebThe moment of inertia is a physical quantity which describes how easily a body can be rotated about a given axis. It is a rotational analogue of mass, which describes an object's resistance to translational motion. …
