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

简单机器有六种基本类型，先从面开始介绍。

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

“这叫做面，”他说。

The massive ball rolls slowly down the inclined plane.

1. 大球沿着面缓慢滚动。

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

他再次弯下腰站在有大理石的面上。

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

“那么行星是在面上的弹珠吗”？

Alberto got up and put the inclined plane away again.

托起身，又把面收了起来。

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面的路径相对应的轨迹。

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， 并在一个的面上滚动到一个特定的位置。

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物体。

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 我不想变成一个面绕轴螺旋状转上几圈之后的样子。

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.

面几乎可以是任何物体——坡、滑梯，甚至只是一块木头——只要它由一个的表面组成。

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.

当你想要举起重物时，面可以提供机械优势：将物体沿面向上推所需的力小于直接举起物体的重量。
