And tin for gay shell torques and such.

以及用于 gay shell 扭矩等的锡。

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

梯子没有旋转， 所以它上面的任何扭矩加起来都必须为零。

In other words, the net torques must be equal to zero.

也就是说，净扭矩必须为零。

A classic example of forces and torques cancelling each other out, is a ladder leaning against a wall.

褪色的经典例子 权力，是搁在墙上的梯子。

And we know that both of those torques equal each other, because the net torque on the ladder is zero.

我们知道这两个时刻是相等的，因为结果 施加在梯子上的扭矩为零。

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。

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

在一项运动中，时机和流畅的执行是必不可少的，但了解足够的物理，特别是质心的扭矩也是必要的。

We don’t know how strong it is. But we can figure that out, by thinking about the torques acting on the ladder.

我们不知道它有多强。 但是我们可以通过考虑作用在梯子上的扭矩来解决这个问题。

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。

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

因此，一旦您知道一个物体处于平衡状态， 您就可以使用该事实来找出作用在该物体上的力和扭矩。
