WebMay 30, 2024 · Rectangles by definition have 0 for their product of inertia. So, the product of intertia for the angle is simply the area of the rectangles times the distance between the centroid of each rectangle in both x and y directions: WebMoment of inertia: I = 1 12 m L 2 = 1 12 ( 1.0 kg) ( 0.7 m) 2 = 0.041 kg · m 2. Angular velocity: ω = ( 10.0 rev / s) ( 2 π) = 62.83 rad / s. The rotational kinetic energy is therefore K R = 1 2 ( 0.041 kg · m 2) ( 62.83 rad / s) 2 = 80.93 J. The translational kinetic energy is K T = 1 2 m v 2 = 1 2 ( 1.0 kg) ( 30.0 m / s) 2 = 450.0 J.

These distances will be at a minimum at the centroid and will get larger as we move further from the centroid. Though this complicates our analysis, the nice thing is that the change in the moment of inertia is predictable.

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. …

WebThe unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square. In the U.S. customary system, m is in slugs (1 slug = 32.2 pounds) and r in feet, with I expressed in terms of slug-foot square.
