| 释义 | moment of inertia Symbol I. The moment of inertia of a massive body about an axis is the sum of all the products formed by multiplying the magnitude of each element of mass (δm) by the square of its distance (r) from the line, i.e. Im = σr2δm . It is the analogue in rotational dynamics of mass in linear dynamics. The basic equation is T = Iα , where T is the torque causing angular acceleration α about the specified axis |
