Moment of inertia of some regular bodies
WebMoment of Inertia We defined the moment of inertia I of an object to be I = ∑imir2 i I = ∑ i m i r i 2 for all the point masses that make up the object. Because r is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis. WebThe polar moment of inertia, J, of a cross section is an indication of a structural member's ability to resist torsion about an axis perpendicular to the section. The polar moment of inertia for a section with respect to an axis can be calculated by: J = ∫ …

WebFrom this expression, it follows that the moment of inertia with respect to an arbitrary point is minimum when the point coincides with G. Hence, the minimum value for the moment of inertia is IG. Radius of Gyration It is common to report the moment of inertia of a rigid body in terms of the radius of gyration, k. This is defined as k = r I m, Web23 jun. 2024 · Moment of inertia. The moment of inertia, or more accurately, the second moment of area, is defined as the integral over the area of a 2D shape, of the squared distance from an axis: where A is the area of the shape and y the distance of any point inside area A from a given axis of rotation.
