After pushing it back into the villa's yard, they got to work.
Because we had already built up a base of fans who liked mechanics yesterday, the number of people increased even more than yesterday.
After four hours of work, the modified bicycle was finally completed.
Chien Chih-chen demonstrated his car to the audience while explaining its principles.
"The principle of bicycle balance is the gyroscopic effect, so when the bicycle wheels stop turning, the balance is broken, and the rider is prone to falling. My improved bicycle uses a different balance principle in its core components. When the line of action of gravity deviates from the fulcrum, gravity will generate a resisting torque on the fulcrum to maintain balance..."
Speak like a human being.
Chien Chih-chen: "Oh, it's the principle of a roly-poly toy."
If you had said so earlier, we wouldn't have needed to use so many words!
[Quick, quick, let's do a simulation experiment. I want to see if it's true that even if you fall apart, you can still maintain your balance.]
Jian Zhizhen nodded obediently: "Okay. Next, I will simulate high-speed impact and high-altitude fall."
She cut open the rubber mannequin's stomach and stuffed a bunch of stones inside to keep the mannequin's weight at 50 kilograms.
Then, the model's knees are cut open and electric power wheels are installed, so that the model's legs can simulate the movement of a person riding a bicycle.
After testing the model, Jian Zhizhen strapped the model to the modified bicycle.
Then adjust the speed of the drive wheel to the fastest.
The bicycle shot off and crashed heavily into the courtyard wall in front of it.
To make it easier for the bicycle to fall apart, Chien Chih-chen deliberately left some screws loose.
The bicycle broke apart after the impact.
Then... a miracle really happened!
