在大兴安岭林区,过去由人工抬木头时,有一种怪现象,六个人抬不动木头,撤下两个人,留下四个人抬,反倒抬起来了。特别是抬着木头上高走跳板,一般都是四个人,前边两个,后边两个。开始我弄不懂,明明是人多力气大,如今这抬木头,六个人怎么会不如四个人呢? 老工人讲,问题就出在中间多出的两个人,他们俩人一用力,前后都受益,所以前边后边的人都想把重量让中间的两人多 In the Greater Xing'an Mountains, there was a strange phenomenon when the wood was raised by hand in the past. Six people could not lift the wood, two people were removed, four people were left behind, and the other people were lifted up. In particular, carrying wood on a high jump board, are generally four people, the front two, behind two. At first I did not get it. Obviously, people are more energetic, and now it carries wood. How can six people be worse than four people? The old workers say that the problem lies in the middle of two people, both of whom work hard Benefit, so the people behind the front want to give the weight of more than two people in the middle
