Then I picture twisting my upper body in the opposite direction I intend to spin, generating torque before I allow it to snap back the other way.

然后，看到自己反向扭转上半身，做出想要的翻转动作，产生力矩，直到再让身体从另一个方向转回来。

This calculation is a little bit complicated because it involves her moment of inertia, which is the rotational analog of her mass.

这个计算有点复杂，因为涉及到她的惯性力矩，这是她质量的旋转模拟值。

Generative AI it has a little black box moment, and that black box can become larger.

生成式人工智能它有一个小黑盒子力矩，而这个黑盒子可以变得。

I'm playing with how we're going to apply a twisting torque to their feet.

在琢如何的脚施加扭转力矩。

Knowing the torque for a given angle made it possible to measure the gravitational force.

知道某一角度下的力矩，就得以测量引力小。

We have a load cell where we're measuring forces in the neck, forces and moments.

有一个称重传感器，用来测量颈部的力、力和力矩。

Now because rotating the satellite is critically important, for a backup, and to help unspin these flywheels once they get to their max rotation speed, we've also got three torque rods again, all oriented 90 degrees to each other.

现在， 由于旋转卫星至关重要，作为备份， 以及在飞轮达到最旋转速度后帮助其减速，再次配备了三根力矩棒，彼此之间呈90度角布置。

If we apply a net torque, so if we are applying a force, remember that is perpendicular to the lever arm, if we apply a net torque that is going to be equal to the rotational inertia.

如果施加一个净力矩，也就是说施加的力是垂直于力臂的，那么这个净力矩就等于旋转惯性。

Timing and smooth execution are essentials in the sport, but understanding of physics, particularly the torques and the center of mass, is also necessary.

时机和流畅的执行是这项运动的关键，但理解物理学知识， 特别是力矩和重心，也是必要的。

The ladder isn't rotating, so any torques on it have to add up to zero.

梯子不旋转，所以力矩的总和 应用于它的旋转等于零。

Mj represents the bending moment at j-th joint.

Mj 表示第 j 个关节处的弯曲力矩。

The maximum load moment of this enormous crane is 275,577.8 tons, and it can lift 5511 tons.

这台巨型起重机的最负载力矩为275,577.8吨，它可以吊起5511吨的重量。

And so if we take an object and apply a net torque to it, what we get is rotational motion.

如果一个物体施加一个合外力矩，就会得到旋转运动。

So, once you know that an object's in equilibrium, you can use that fact to find the forces and torques acting on it.

所以当你知道元素是平衡的，你可以 那是从影响它的力和力矩的计算中得出的。

This crane can lift an astounding thanks to its maximum load moment of 250.000 metric tonnes.

这台起重机能够吊起惊人的重量，得益于其最负载力矩达到250000吨米。

And then finally could you test the relationship between torque, time and change in angular momentum?

然后你能测试力矩、时间和角动量变化之间的关系吗？

It is going to start to lose some of that angular momentum and as it does that the force of gravity is going to apply a greater torque and it will eventually fall down.

它将开始失去部分角动量，随着角动量的减少，重力会施加的力矩，最终它会倒下。

For example: you could also apply what's known as shear stress.

。也可以应用 所谓的剪切力矩。

So if we look at it from above, when you apply a force in this direction, so that is a torque, what you are doing is applying a force for a given period of time.

所以如果从上方看， 当你在这个方向施加一个力，那就是一个力矩， 你实际上是在一段时间内施加了一个力。

So change in angular momentum is simply equal to the torque times the change in time.

所以角动量的变化就等于力矩乘以时间的变化。
