《荒野求生》之跟着贝尔去冒险第441期:机械省力

 What I can do is just fill my rucksack full of sand and then bury it. 我能做的就是 用沙填满我的背包  并把它埋起来

And that will be my deadweight that I can haul against. 用它作吊车的自重

Just pull off a length of rope. 再扯段绳子下来

Two bits of plastic are hosing just from the trash on the beach. 这有两段塑料 它们是我从海滩上的垃圾中淘的软管

Fit those together, and that will act just like a roller. 把它们套起来  等会就用它们作滚筒

And now you got two of those.Run a rope around that. 现在有两个了 把穿绳子穿进去

And that's gonna help just reduce friction¹. 它能减小摩擦

Okay.That's the strong point. 行了 支撑点也有了

Now this runs out to the dead anchor. 把它连上锚点

Each time you loop the rope,The load you have to pull is reduced. 绳子每多绕一圈 所需拉力就减小一倍

It's called mechanical advantage. 这便是机械省力的原理

And just thread it through this roller. 让它穿过这个滚筒

That will almost give me the pulling power of three men instead of just me. 有了它的帮助  我一个人的拉力 将拥有三人同拉的效果

Okay. Come on, then. We can do this. 好了  加油  我们能行

Come on. We can do this. We're so close now. 加油  我们能行  很近了

Come on. We can do this. Okay. 加油  我们能行  行了

It's at the limit,And then we're gonna need to set this again 绳长到极限了 还要再来一遍

Another 10, 15 yards right that way.Just do it in little stages. 要再往那边移10或15码 得一步一步来

 

1 friction   

n.摩擦，摩擦力

参考例句：

• When Joan returned to work,the friction between them increased.琼回来工作后，他们之间的摩擦加剧了。
• Friction acts on moving bodies and brings them to a stop.摩擦力作用于运动着的物体，并使其停止。
