Moment of inertia,转动惯量
In subject area: Engineering Inverse dynamics is a method for computing forces and torques based on the kinematics of a body and the body’s mass and moment of inertia (Winter, 2009). From: Biomechanics and Gait Analysis, 2020 About this pageSet alert ...
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 a torque (turning force). The axis may be int
A generic expression of the inertia equation is I = k m r2(2c) where k = inertial constant - depending on the shape of the body Radius of Gyration (in Mechanics) The Radius of Gyration is the distance from the rotation axis where a concentrated point mass equals the Moment of Inertia ...
Moment of inertia, abbreviated as I, also called rotational inertia, measures the resists or change an object has to rotational acceleration about an axis. It is analogous to the mass of an object in linear motion and plays a similar role in rotational dynamics. The larger the moment of in...
