When we were in school, we all learned to pulley. So, do we really know anything about pulleys? Pulleys are not complicated, there are only two types: movable pulleys and fixed pulleys.

The difference lies in whether the central axis is fixed or not, and whether it saves effort. The encyclopedia entry says that the fixed pulley is neither labor-saving nor labor-intensive, so I am a little puzzled.

You say it's effortless, and I understand it well, but why add effortlessness? What does this phrase mean?

Does it have something to do with the shape of the pulley? Switching to a square one will be laborious. Well, that's how it should be explained.

Movable pulleys can save half the force, but the length of the rope will be doubled. That is to say, the physical work done by the pulley remains unchanged.

We know that pulleys are all round, but what happens if a fixed pulley is a Lelo triangle?

Since the Lelo triangle can be the shape of a bicycle tire, why can't it be called the shape of a moving pulley?

I think it can save effort, but how much you save will need to be experimented. Mizukawa was the first to speak.

A little imaginative. I often hear that physicists bombard what particles are, and I also come to do a thought experiment.

Can a certain point of the fixed pulley rotate with an electronic fix? What is the lower limit of energy required for rotation is the key to this question.

If the lower limit is close to infinitesimal then the energy of the electron can definitely exceed the lower limit. Although it is possible to move, the estimated speed is slow.

As electrons are negatively charged, protons are positively charged. The protons in the fixed pulley must attract this electron, and the position of the electrons becomes the lowest part of the fixed pulley after the fixed pulley moves n times.

A single pendulum is involved in this process. If the fixed pulley is near a very large celestial body, then the fixed pulley will definitely rotate in waves.

Note that the fixed pulley is extremely resistant to decomposition. So, don't worry about it being broken down by gravity. First of all, fluctuations are super-large celestial bodies that distort space-time.

Secondly, the rotation is because of the enormous gravitational pull of the super-large celestial body. Margarita didn't say much, but it was shocking enough.

The reversing speed of light is 3×10⁻⁸ meters per second, which is the reciprocal of the value of the speed of light. Why is the inverted speed of light proposed?

I think that objects move very slowly, and shadows can also occur. It's just that time gets fast. That's right, it's the opposite of the relativity clock-slow effect.

I imagined two objects moving at the speed of light and light, respectively, and exerting an influence on a fixed pulley at the same time.

So, what happens to fixed pulleys? There are three scenarios. One is that the fixed pulley begins to move at the speed of light.

That's understandable! The nature of slow movement is assimilated by the fast movement. The second is that the fixed pulley moves at the speed of inverted light.

It's hard to understand. Why is it better to exercise fast than to exercise slowly? The third is that the pulley is not affected in any way.

I'm leaning towards the third. Of course, I don't yet have a clear answer as to how exactly inverted light motion and light speed motion affect each other.

In the future, there may be physicists who can give the answer. The idea of the six sons of the wind is very bold.

。 A pulley a is fixed on the ground, and a pulley b is fixed on the inner top surface of the building. And make the chute direction of the two pulleys consistent.

Pass through the bottom of the pulley side A from its side. Then pass through the top of pulley B on a vertically unoriented side.

Pull the object with a rope on side A to achieve the purpose of saving effort. I think the discussion is getting more and more like a keynote presentation, but it's good.

With all that said said, what are you still doing here? Dueñas asked, and the three were gone.
