This is intended to help us understand the concept of a moment of … WebbFigure 10.25 Calculation of the moment of inertia I for a uniform thin rod about an axis through the center of the rod. We define dm to be a small element of mass making up …
WebbMoment 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 … WebbA more common method to find the moment of inertia is by parts. Like finding the centroid (needs to be done first), the object is split into smaller basic shapes. The moment of inertia about the centroid of each part can be found in a handbook (see Appendix Sections ).
WebbStep 1: Divide the whole area into regular shapes. we opt to use the square(red), quarter-circle (Blue) and triangle (green). Locate the centroid of each area from the x and y axis. Step 2: The moment of inertia will be simply the summation of moment of inertia of
