There are six basic types of simple machines, starting with the inclined plane.

简单机器有六种基本类型，先从斜面开始介绍。

We just finished this problem with the pulleys and the inclined plane.

我们刚完了带有槽轮和倾斜平面的问题。

He stood bowed over the inclined plane with the marble again.

他再次弯下腰站在有大石的斜面上。

" This is called an inclined plane, " he said.

“这叫斜面，”他说。

Let's say we are applying a force up the inclined plane.

假设我们正在沿着斜面施加一个力。

He was doing really detailed experimentation with inclined planes.

他正在用倾斜平面非常详细的实验。

And as well as a parallel feed to the inclined planes.

并且还设有与斜面平行的给料装置。

Alberto got up and put the inclined plane away again.

阿尔贝托起身，又把斜面收了起来。

But rather rolled these balls down an inclined plane and varied the amount of mass.

但却是把这些球滚下斜面，并改变了球的质量。

" Are the planets marbles on an inclined plane then" ?

“那么行星是在倾斜平面上的弹珠吗”？

And so you can think of this almost like an inclined plane.

你可以把这几乎想象成一个斜面。

So we will have described a trajectory corresponding to the marble's path across the inclined plane.

因此，我们将描述与弹珠穿过倾斜平面的路径相对应的轨迹。

And so I did what Galileo did, I started using inclined planes.

于是我了伽利略过的事情，开始使用斜面。

Thus the wheels come from one part of the factory and are rolled on an inclined plane to a particular spot.

因此，车轮来自工厂的一个部分， 并在一个倾斜的平面上滚动到一个特定的位置。

No misunderstanding. I've learned what that request actually means, and I don't want to be joined to another object by an inclined plane wrapped helically around an axis.

我没误会 我了解到那个要求意味着什么 我不想变成一个斜面绕轴螺旋状转上几圈之后的样子。

And so now I have got that same tennis ball, but it is on an inclined plane.

现在我有了同一个网球，但它是在一个斜面上。

Galileo's Two New Sciences requires you to imagine, or to repeat for yourself in a laboratory, certain experiments with inclined planes.

伽利略的两门新学要求您想象或在实验室中自己重复某些斜面实验。

Like inclined planes, pulleys are used to gain a mechanical advantage: objects are easier to lift using a pulley system than by using your own two hands.

和斜面一样，使用滑轮是为了获得机械优势：使用滑轮系统比使用你自己的双手更容易举起体。

An inclined plane can be pretty much any object — a ramp, a slide, or even just a block of wood — as long as it consists of a sloping surface.

斜面几乎可以是任何体——斜坡、滑梯，甚至只是一块木头——只要它由一个倾斜的表面组成。

Helpful when you're trying to lift heavy objects, the inclined plane offers a mechanical advantage: the force required to move an object up the incline is less than the weight being lifted.

当你想要举起重时，斜面可以提供机械优势：将体沿斜面向上推所需的力小于直接举起体的重量。
