Moment of inertia,转动惯量
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...
(A.19)I=mr2 In general, when an object is in angular motion, the mass elements in the body are located at different distances from the center of rotation. The total moment of inertia is the sum of the moments of inertia of the mass elements in the body. Unlike mass, which is a con...
section moment 就是截面力矩哦 area moment 是面矩，很明显的不同， section 表示部分，而area是区域 希望对你有帮助哦~截面
翻译 section moment of inertia 翻译 截面惯性矩 以上结果来自机器翻译。 释义
For the I-shaped section, however, it is not possible to simply subtract the smaller rectangles from the larger, as was done when computing the moment of inertia about the x-axis, since the centroids of the various parts being subtracted do not coincide. Instead, one must add the three ...
