This kind of tear right here is a beveled or a scarf tear.

这种撕裂是或围巾撕裂。

Someone please show me a proper sloper technique.

请来个人给我展示一个正确技术。

And a sloper is like a very sloping hold.

就是一个非常倾着力点。

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

简单机器有六种基本类型，先从开始介绍。

Or you divide both sides by mass, you get force over mass is equal to acceleration.

这个力，也就是平行於这个地心引力分力这个力，也就是平行於这个地心引力分力。

The last stage is honing and putting a very fine edge or bevel.

最后一步是用磨刀石磨，继而得到光滑边缘或。

That will give you our acceleration.

这个力，也就是平行於这个地心引力分力。

And the direction going into the surface of the plane.

往进入方向。

So then you get your acceleration.

这个力，也就是平行於这个地心引力分力。

Your acceleration is going to be 4.9 meters per second squared.

这个力，也就是平行於这个地心引力分力。

And this is parallel to the plane.

既然它会垂直於他也会垂直於这个平行分力。

So maybe there's some normal force that's completely netting it out in this example.

如果没有维持它在上摩擦力如果没有维持它在上摩擦力。

The function of pyramids changes between groups and cultures, and often they will be stepped rather than flat-sided.

金字塔功能因群体和文化不同而不同，它们通常是阶梯式，而不是有着平滑。

But thanks to our skillful coxswain, we were fouled on the bias rather than broadside, so we didn't capsize.

这水必须排出去。由于艇长机灵，艇身只是而不是正受到海马攻击，所以没被憧翻沉没。

And when the block was stationary, we said there must be an offsetting force.

这个力也就是49牛沿向上摩擦力，这个力也就是49牛沿向上摩擦力。

The scientists used high-speed video cameras to record the position of the snakes as they moved sideways up different inclines.

科家使用高速摄像机记录蛇在不同上升时位置，这种运动叫蛇形。

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

“这叫做，”他说。

Alberto got up and put the inclined plane away again.

阿尔贝托起身，又把收了起来。

But the rest of it fitted intothe cant well enough.

但它其余部分很适合这个。
