12s

12s is my homework in the first semester. The job is to ask us to make a device that can accurately measure 12 seconds. It was almost silly to start getting this topic, and I didn't know what to do. Because it was a group assignment, my teammates and I decided to paint some ideas first, and then exchange them in a concentrated way to select from them. We have drawn a lot of sketches, but the overall thinking is probably the same, using gravity. In the end we decided to use sand to make an hourglass-like device. Because it is better to control the sand than water  to make a simple model. The time spent is longer than expected, but the final results are pretty good. A certain amount of sand is poured into the funnel, and then through the principle of gravity and leverage, the small bell above will ring in about 12 seconds. I thought that when I was reporting that day, everything was going well. I didn't expect my teammates to accidentally drop the model at home, and I was so anxious that I burst out. But fortunately he take the model before the end, and our model is also the most accurate time of the game. Relative to our model, I also found a lot of interesting.Something like useing air currents and useing thermal expansion and contraction. It's was very interseting.

 


12s 

12s是我在第儿学期的一个作业。作业的要求是要我们做一个器械,这个器械能够精准测量12s这个时间。刚开始拿到这个题目都快傻了,完全不知道该怎么办。因为是小组作业我和我的组员决定先自己画一些想法,然后在集中交流,从中挑选。我们画了不少的草图,但总体思路都大概一一致,都是利用重力。最后我们决定利用沙子制作一个类似沙漏的装置。因为相对于水,沙子比较好控制完了之后就是制作简单的模型。时间耗费的比想象中要久了多,但是最后出来的效果还算不错。在漏斗里倒入一定量的沙子,然后通过重力和杠杆原理,在12s左右的时间会敲响上面的小铃铛。本以为那天作报告的时候一切顺利,可没想到我的组员不小心把模型落在了家里,急得我爆粗口。但好在他在临近结束前把模型送到,我们的模型也是全场计时最精准的。相对我们的模型,我也找到很多很有意思的。有利用气流的,有利用热胀冷缩的,非常有意思。
