Chapter 424: The Principle of Leverage! Ask Huangshi Gong to teach you a lesson
"There are several problems with this picture of yours." Su Yu rubbed his chin, and his face was both surprised and confused.
He was delighted that Qiyu, the little old man, was always able to make some epoch-making suggestions.
Su Yu even wondered, did Qiyu also travel from the future?
Look at what he has come up with during this time.
The motor vehicle, and its simple yet ingenious steering structure.
Paddle wheel power structure applied to steam engine.
And today's crane concept.
Take out one of these at random, even if it is placed in a thousand years, it will be an appalling existence.
It seems that these ancient people in the Daqin period were not unintelligent.
Rather, there is no environment in which "seven, six, seven" can fully function.
After all, like this kind of mechanical structure, there is no main power source to drive, no matter how delicate it is, it is just a decoration, and it is useless.
The emergence of the steam engine today is like a spark that ignited the fuse.
The Mo family, who had been silent for a long time, and a group of folk masters finally had a place to use them.
But then again, sometimes thinking too far ahead is not a good thing.
This is also the question Su Yu is struggling with at this moment.
That is, with the materials you have now, can you support the rest of this idea?
As we all know, such a lifting device has extremely strict requirements on materials.
With a little carelessness, the boom, which carries a great weight and is extremely long, will collapse in an instant.
In today's Daqin, metallurgy has just started.
According to Qiyu's vision, this boom will lift a weight of five hundred stone, which is equivalent to several tons.
Plus the boom weight of the steel structure.
Based on the steel made by the current method of pouring steel, and the structure on the picture of Qiyu, I am afraid it is difficult to bear such a weight.
"Immortal, what's the problem?"
Seeing Su Yu frown slightly, Qi Yu's heart sank.
And Lao Zhao and others also began to have doubts in their hearts.
Could it be that Su Yu found something lacking in it?
"Look here." Su Yu pointed to the base of the boom in the drawing.
"Here I personally think that it should be bolded as much as possible, and I don't know if it will work."
"If this doesn't work, you can only use this crane after the development of Daqin in the future. 39
Qi Yu looked at the location Su Yu pointed to, frowning tightly.
Thinking that he had tested it again and again, he dared to say: "Immortal, I know what you are worried about."5
"I have tested the steel column at the root, and it can definitely withstand the weight of the cargo and the steel wall.
Seeing Qiyu's confident look, Su Yu couldn't help but begin to doubt himself.
Could it be that he miscalculated?
Or maybe he underestimated the strength of Daqin steel?
Su Yu asked subconsciously, "How did you test?
Seeing Su Yu asking, with a hint of uncertainty in her tone, Qi Yu was instantly full of confidence, patted her chest and said:
"I found Daniel and asked him to help cast the end of the steel arm of the same specification first."
"Then we used the end of the steel arm to successfully lift a weight of 800 stone.
"So with the design of the steel column in my drawings, there is absolutely no problem with the strength.
Su Yu reluctantly wiped his face, thinking in his heart that it was true.
With their method, naturally there is no problem.
The base of the steel arm, which can lift eight hundred stone, is used to support a crane that lifts five hundred stone, which seems to be no problem.
However, Su Yu knew very well.
Where is this no problem?
It's obviously a big problem, okay?
They overlooked an extremely important issue...
That's... the principle of leverage!
Because of the length of the force arm, the force of the material at the end of the boom is actually several times that of the front section of the boom.
The problem is far from being as simple as adding up.
However, in Qiyu's vision, the force of the material at the end is nothing but the weight of the steel arm itself and the cargo.
And such a problem does not only exist at the tail end of the boom.
Instead, in each segment of a separate scalable structure, the tail of the structure has such a problem.
It's just that this is most obvious at the tail end of the entire boom.
It is conceivable that if this crane is really built, it will absolutely collapse during the experiment.
At that time, Qi Yushao couldn't stand the punishment.
This is also the reason why ideas that are not suitable for being too advanced are born in every era.
Ideas and designs are often supported by a large number of theories.
Theoretical knowledge is not in place, the vision is not broad, and there is no idea to say.
But if it is like Qiyu, the idea is very advanced, but there is no theory to help him improve.
Then the blow to him in 5.0, whether it comes from the above punishment or self-doubt.
For a "scientist", it is often fatal.
If Qiyu hadn't come to ask with the blueprint this time, he, a mechanical genius, might have been left in the dust.
"Hey... let me make a suggestion." Su Yu sighed and suddenly changed the subject.
Everyone was slightly taken aback.
Aren't we talking about cranes now?
What advice would Su Yu give at this time?
"Qiyu, when you are free, you and your people from the Young Mechanical House will send someone to ask Huang Shigong to come back and teach you a lesson, and then continue the research on this crane."
