What is Moment of Inertia?
Moment of Inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of torque (turning force). The axis may be internal or external and may or may not be fixed. The moment of inertia (I), however, is always specified with respect to that axis and is defined as the sum of the products obtained by multiplying the mass of each particle of matter in a given body by the square of its distance from the axis. In calculating angular momentum for a rigid body, the moment of inertia is analogous to mass in linear momentum. For linear momentum, the momentum p is equal to the mass m times the velocity v; whereas for angular momentum, the angular momentum L is equal to the moment of inertia I times the angular velocity ω.
How to Calculate Radius of Gyration of I Cross Section about xx Axis?
Radius of Gyration of I Cross Section about xx Axis calculator uses Radius of Gyration of I Section About XX Axis = 1.78*Thickness of Flange And Web of I Section to calculate the Radius of Gyration of I Section About XX Axis, Radius of gyration of I cross section about xx axis is defined as the radial distance to a point from xx axis that would have a moment of inertia the same as the body's actual distribution of mass. This formula suits an I section with a Width=4*t and Height=5*t. Radius of Gyration of I Section About XX Axis is denoted by kxx symbol.
