moment of inertia

单词moment of inertia

基本解释

na.: 惯性矩；【物理学】转动矩量
网络: 转动惯量

英汉解释

• 惯矩

• 惯性矩

例句

• But it"s completely different, the moment of inertia, if you rotated it about this axis.

  但它完全不同，转动惯量，如果将其绕这轴旋转。

• Well, we will try to compute now the moment of inertia about this point.

  我们要去计算关于这个点的转动惯量。

• The moment of inertia about the x-axis is going to be obtained by integrating y squared times the mass element.

  对于x轴的转动惯量，就可以由对y^2*质量元做积分得到。

• Well, it is one of the important things of solid mechanics, which is the torque of a force divided by the moment of inertia.

  这是固体力学的研究重点之一，就是力的扭转力矩与转动惯量之比。

• If I know the moment of inertia, then I know how much rotational kinetic energy there is.

  若知道转动惯量我就能知道，转动动能是多少。

• We have the mass of the sun, we have the radius of the sun so you can calculate the moment of inertia of the sun.

  我们知道太阳的质量，太阳的半径，所以可以计算出，太阳的惯性是多少。

• the platform can analog rolling and swaying motion of ships . the moment of inertia , damping and restoring force can be adjusted.

  该试验台架能够模拟船舶的横摇运动和横荡运动，试验台架的转动惯量、阻尼力矩和恢复力矩可调。

• The final formula for the moment of inertia about the origin is the double integral of a region of r squared density dA.

  关于原点的转动惯量，就是在区域上，求r^2*δ*dA的二重积分。

• For the moment of inertia, we want the square of a distance to the axis of rotation.

  至于转动惯量，要求的其实是到旋转轴距离的平方。

• It has to do, of course, with the moment of inertia, but again, it"s independent of mass, radius and length.

  肯定是，与时间惯量有关，再次，它与材料无关，还有半径和长度无关。
