In Chengdu, Sichuan Province, a man did a physics experiment to prove that the legendary three matchsticks hoisted a bottle of water, which seemed simple, but the physical principles in it were very profound.
The man first placed a small bench on the ladder, pressed the first matchstick with an iron block, and then hung a 250 ml bottle of drink. The second matchstick is across the middle of the rope, the third matchstick is erected between the first and second matchsticks, and the experiment is completed by removing the iron block.
This experiment uses the fulcrum point, changes the force point, using the principles of physics, the tilt of the matchstick changes the direction of the force point, it becomes the role of the hook, the structure changes the direction of the force, the center of gravity is smaller than the structural force point, equivalent to a hook less than 90 degrees hanging there, so that the matchstick hangs a bottle of water.
Netizens said: This is OK, the key should be the center of gravity line, under the board of the bench.
Some netizens also said: The standing matches and ropes form an angle, so that the whole forms a hook force of the center of gravity offset.
Some netizens said: The matches on the stool are obviously glue, and you old iron shoot videos!
