On October 31st, the East China University Physics Competition began!!
The venue of the competition happened to be at Liu Shao's Jiangnan Province University of Technology. Why was it here?
Because it was relatively fair.
In the entire East China region, other than Lin 'an University, there were two other schools that were very close to Lin' an University. One was Shanghai University, and the other was Eastern University.
In order to avoid the host's home advantage, no school agreed to compete with the other two schools. Naturally, it fell to Jiangnan Province University of Technology, the second tier in the East China region.
Although it was a good thing to hold such a competition, the teachers and students of Jianggong University felt that they were looking down on them.
Does it mean that our home ground advantage doesn't affect your three schools at all?
Indeed, it did not affect him at all!
This was because the first and second prizes of the competitions over the years were almost all students from these three schools.
Occasionally, some students from other schools would win the third prize.
However, most of the ordinary schools only gave outstanding awards. What was worse was the participation award.
One had to know that those who could participate in the East China Regional Competition were already outstanding students in many schools.
At 7:30 pm, a bus stopped at the entrance of the university.
The twenty-one students who participated in this competition took the bus to the examination hall of Jiangnan Province University of Technology.
Ouyang Xiao didn't like the strange smell in the bus, so he wore a black mask out of habit.
Once he got into the car, the originally handsome him instantly turned into a shiny baby with the help of the mask!
However, the students on the bus were the kind who were addicted to studying. No one gave him a second glance. He was so handsome that he felt lonely.
Ouyang Xiao casually found a seat and sat down. He turned on his phone and scrolled through the Android software platform. The number of downloads of Hammer had reached more than 80,000.
A few days ago, Ouyang Xiao had seen the exaggerated number of people in the live streaming world when he started a live broadcast to advertise "Hammer".
It clearly showed that there were more than 700,000 viewers, but in reality, there might not even be 70,000!
It really wasn't an exaggeration!
Ouyang Xiao had been livestreaming for three hours and had been recommending 'Hammer'.
Most of the comments on the bullet screen were,[I'll definitely download it later!]”
But in reality?
The number of downloads only increased from 11,000 to 12,000 the next day!
All of them were just talking but not doing anything!
On the other hand, Meng Xiaoqi had managed to recruit more than 20 clubs, including the Youth Association, Science Association, and Student Union!
As for how she got it, she smiled and didn't say much.
It was fine if he didn't want to say it. Ouyang Xiao was only curious about his studies. He didn't care about anything else.
Fortunately, after " Hammer " was updated, it attracted the participation of some clubs and users. There were still around 3,000 to 4,000 downloads a day.
At 8:30 pm, the bus arrived at the examination hall of Jianggong University.
When they got out of the car, the entire examination hall and teaching building had been surrounded by horizontal bars. Several security personnel were still maintaining order.
There were quite a number of people in the examination hall. It was said that 15 universities were participating, and the number of people was close to 300.
Ouyang Xiao prepared his exam documents and entered the classroom to wait for the exam.
In terms of learning efficiency, Ouyang Xiao had really finished studying quantum mechanics, electrodynamics, atomic physics, and material physics. In addition to the first few courses he read, he had already mastered most of the physics content.
For this kind of pure mechanics exam, the knowledge reserve was enough.
At nine o'clock sharp, the examination bell rang.
The invigilator handed out the papers.
Everyone took the test papers and quickly looked at the questions!
The exam time was two hours, but there were only four questions!
That's right, you only need to finish writing one message in half an hour.
However, in reality, many students only wrote for half an hour. The remaining hour or so was spent in a daze or pretending to write.
However, this year's questions were even more abnormal. The students in the examination hall were dumbfounded!
He had no way to start with the first one!
To exaggerate, this paper shocked the entire world!!
If I explode at the start, it's useless even if you give me a trillion!
Of course, if there was really a trillion, who would write this?
I'm going to find seven beautiful sisters to play a Mini games. Isn't that nice?
For the first question, the zoo was going to have a monkey acrobatic performance. The monkey trainer designed the following devices: In the vertical plane, a ring with a smooth sliding groove and a radius of R was fixed. A uniform rigid rod with a weight of P and a length of l=3R was placed in the ring sliding groove, so that a monkey with a weight of Q could walk along the rod. It was known that P= 2Q. Try to find the equilibrium position of the rod when the monkey is at a distance of d from the end point A of the rod? (Expressed by the angle between the rod and the horizontal line.)
Many examinees felt very angry. Don't you think it's annoying to meet such a monkey that moves around?
The question was clear, but it felt like it was missing some conditions. He held the pen in his hand, but he couldn't write!
Of course, the questions for the provincial competition weren't too difficult. There were still quite a few university geniuses who started writing.
Ouyang Xiao looked indifferent. He even felt that he had overestimated the physics level of university students.
He sighed and wrote down two solutions:
The first solution was to find the equilibrium position of the monkey-rod system by using the analytical statics method and the virtual displacement principle. After establishing the coordinate system, the monkey's position was represented by K. Furthermore, since A and B were ideal constraints, the binding forces UA and NT did not work at the corresponding virtual position shift, and the system only had gravity to do work. It could be solved by the center of mass C of the rod and the distance between the center of mass O and the center of mass C of the rod.
The second solution was even more convenient. It used the rigid body statics method and directly solved the equilibrium equation. After he finished writing the five-element equation, he directly gave the answer.
This kind of exam did not allow one to hand in the paper in advance, so Ouyang Xiao could only write a few more solutions to pass the time.
