【每日一篇】《泰坦尼克号》的完美结局？
前一段时间，有人发微博说其实电影《泰坦尼克》的最后女主角Rose上的那块木板有很大一片地方让两个人都躺上来，这样就是个完美结局了！这个理论真的可以吗？今天我们一起来揭晓！http://www.taisha.org/test/today_read/photo/2012F04F20816801311.jpg

拍这张图片的应该是个建筑学的同学，因为他们忽略了最简单的物理学原理，也就是重力与浮力这一对儿“世仇”。虽然说海水的密度要＞淡水，同理海水的浮力也要略大于淡水，但是如此浮力依然不能满足男女主角的需要。一位同学根据计算得出，女主角最后所乘坐的木板在海水中的浮力有882.9牛顿，可是Jack+Kate所受的重力有1926.684牛顿。不得不说，就算两个人都减肥省骨头架子，那块儿破甲板恐怕也根本不够用……
After watching “Titanic,” many people left the theaters wondering why Jack didn’t live. Couldn’t he share that plank with Rose?
The curious and nerdy people of Reddit decided to tackle this pressing issue. A user ran the math and the short answer is no. Leonardo DiCaprio’s Jack was doomed to die. “As force of gravity is larger than that of buoyancy; Leo and Kate will be swimming with the fishes.”
The calculations show the force of buoyancy (882.9 newtons) is less than that of gravity (1926.684 newtons). Alas, it just wasn’t meant to be.
电影里面好像开始就演到重量问题了吧~~~
