2 . 如图①,将
个完全一样质量均匀长为
的长方体条状积木,一个叠一个,从桌子边缘往外延伸,最多能伸出桌缘多远而不掉下桌面呢?这就是著名的“里拉斜塔问题”.
![](https://img.xkw.com/dksih/QBM/editorImg/2024/3/23/bc879c7d-8f43-4e6c-b6d8-ddd10ad2a335.png?resizew=507)
解决方案如下:如图②,若
,则当积木与桌缘垂直且积木重心
恰与桌缘齐平时,其伸出桌外部分最长为
,如图③,若
,欲使整体伸出桌缘最远,在保证所有积木最长棱与桌缘垂直的同时,可先将上面积木的重心与最下方的积木伸出桌外的最远端齐平,然后设最下方积木伸出桌外的长度为
,将最下方积木看成一个杠杆,将桌缘看成支点,由杠杆平衡原理可知,若积木恰好不掉下桌面,则上面积木的重力
乘以力臂
,等于最下方积木的重力
乘以力臂
,得出方程
,求出
.所以当叠放两个积木时,伸出桌外最远为
,此时将两个积木看成整体,其重心
恰与桌缘齐平.如图④,使前两块积木的中心
与下方的第三块积木伸出桌外的最远端齐平,便可求出
时积木伸出桌外的最远距离.依此方法,可求出4个、5个直至
个积木堆叠伸出桌外的最远距离.(参考数据:
,
为自然常数)
(1)分别求出
和
时,积木伸出桌外的最远距离.(用
表示);
(2)证明:当
时,积木伸出桌外最远超过
;
(3)证明:当
时,积木伸出桌外最远不超过
