Wang Li wanted to speak, but he just thought of the other party's lonely situation, so he finally said nothing more and continued to try the three-piece suit with great interest.
Wang Li's equestrian skills are good. With a three-piece horse suit, a skilled knight like him can completely free his hands on horseback.
This means that fighting on horseback, with a bow and an arrow, is more relaxed and enjoyable.
Zhao Si, on the other hand, is studying the recliners and wheelchairs sent by the craftsmen.
Needless to say about the recliner, it is mainly about design ideas, not too much technical content. Once you go up, it is rickety and very comfortable.
"Zhao Bugeng, try the wheelchair!" Military Craftsman rubbed his hands beside him and said with a smile.
Zhao Si sat on the other party's eager expression, and the craftsman pushed. Zhao Si was surprised to find that when passing through uneven places, the bumps were not obvious.
"How is this done?" Zhao Si stood up and squatted down in surprise, but did not see anything like a spring.
The craftsman finally showed a proud expression for the first time in front of Zhao Si.
"here!"
The craftsman smiled and pointed to the structural position of the wheelchair wheel support shaft.
Zhao Si was surprised to find that there were actually bamboo tubes of matching thickness. When he tried to apply pressure to the wheelchair, he found that the matching bamboo tubes would float up and down with the amount of pressure.
"Is the orifice here? What was used?" Zhao Si said in surprise.
"Bamboo planks!" the craftsman replied.
The craftsman then skillfully disassembled the wheelchair and took out the support shafts of the four wheels.
Two bamboo tubes of different thicknesses are placed inside each other. After being disassembled, there are four bamboo boards inside.
Zhao Si observed carefully and discovered the ingenuity.
The small bamboo tube inside has holes on all sides and is fixed with a wooden core in the middle. The bamboo plates are fixed up and down on the wooden core. As pressure is applied, the bamboo plates will bend outward to provide elasticity.
The four axles are four shock absorbers.
The bamboo sheets act as springs.
Of course, the shock absorption range is very limited. At most, two fingers and two large and small bamboo tubes are in real contact.
"That's it!" Zhao Si also went to school. After taking it apart, he immediately discovered the principle.
"Using the elasticity of bamboo to reduce bumps, the bamboo tubes are in conjunction with each other to provide buffer space for up and down movements." Zhao Si marveled.
This thing is not too difficult to say, but this is the pre-Qin era.
"Zhao Bugeng understands now?" The craftsman had a look of surprise on his face, as well as some frustration that he was interrupted before he could even pretend.
Zhao Si's hands-on ability is indeed not strong, but his "invention" ability is strong!
After Zhao Si arrived at Lantian Camp, not to mention Wang Li, the craftsmen were all shocked from time to time.
Although Zhao Si is not good at hands-on skills, he can talk in a set way, including Zhao Si's unique calculation method, which has now become popular among craftsmen.
The shortcomings of Arabic numerals are obvious, but the advantages are also very obvious. As long as you are familiar with the modern calculation formulas, the calculation efficiency will be improved by more than one and a half points, and the craftsmen happen to be able to use them. Zhao Si teaches without distinction and is happy to spread usefulness in this era. knowledge.
The craftsmen all have a favorable impression of Zhao Si, mainly because in this era when knowledge is directly equivalent to wealth, Zhao Si taught selflessly and made many practical gadgets for them. He also taught them modern composition methods, modern mathematics and applications for free. The formula is no different from the money-spreading boy.
The most important thing is that Zhao Si still has no arrogance in him, and Zhao Si can still understand the knowledge mastered by the craftsmen. It is really hard for them not to love Zhao Si like this.
"Unfortunately, the bamboo boards have poor endurance. If used on a wheelchair, the oil would have to be replaced every now and then. It cannot be used on a chariot!" the craftsman said slightly disappointed.
"What if we use something stronger?" Zhao Si asked with a smile.
"Like gold!"
"How is it possible? Gold is easy to break and hard. It either cannot provide elasticity or it will break." The craftsman shook his head.
"How about changing the shape?" Zhao Si drew the shape of a spring on the ground.
"Is it easy to break like this?"
The craftsman looked at the spring shape on the ground and fell into deep thought.
After a long silence, the craftsman finally said: "I'll try! I'll try! Maybe it's really good!"
After saying that, the craftsman hurriedly bowed and left, not wanting to show Zhao Si the other functions of the wheelchair and hurriedly left. Zhao Si looked at the craftsman's leaving back and shook his head with a smile.
It definitely won't work.
At least the smelting technology of this era is really bad.
Even if it is really rubbed by hand, mass production will be a big problem.
Brass has terrible elasticity, while bronze is only a little better.
The best elastic modulus is steel, but the iron smelted by the primitive iron-smelting technology of this era is extremely brittle, and its elasticity may not be as good as bronze.
The final result may be that the craftsmen have worked hard to create a spring that cannot be mass-produced and has low practicality.
However, this is still very meaningful. At the very least, it is a great progress in turning theory into practice and will point the way forward for future generations.
On the other side, Wang Li ran for a long time, got off his horse, and walked towards Zhao Si with joy on his face.
"Is this a recliner? Let me try it!" Wang Li squeezed up unceremoniously and pushed Zhao Si out with his butt.
The recliner rocked back and forth, and Wang Li almost lost his balance and fell. Zhao Si had no choice but to get up and sit on the wheelchair.
There are no stools these days, so it is really uncomfortable to sit on your knees, but there is no way, etiquette and customs are not so easy to change.
"You can't see the clues about the horseshoes for the moment. I'll let the soldiers lead the horses back and forth through the night, and then we'll know the benefits. This horse's saddle is really a wonderful thing!"
"I can draw my bow and draw an arrow while galloping!" Wang Li said with excitement on his face.
"Ah? Aren't all grassland barbarians like this?" Zhao Si was stunned for a moment.
When Wang Li heard this, he looked at Zhao Si with a strange expression and asked, "Where did you hear this? If all the barbarians in the grassland are like this, how can there be Yan, Zhao, and Qin?"
"It is the most skilled rider who gets on the horse. During the galloping process, he can't even use ten points of strength. He draws the bow and sets the arrow. First, he must reduce the riding speed. Second, he must maintain his body. He shoots the arrow in a hasty manner. There may not be any, and arrows may not run faster than horses." Wang Li explained seriously to Zhao Si.
"Did the barbarians first ride to the bow and arrow range, then stop shooting, then ride back to distance, and so on?" Zhao Si discovered Hua Dian, but it's just that it's funny no matter how you think about it.
The main reason is that Zhao Sizhen doesn't know much about cavalry combat. His understanding of Hu people's tactics is limited to the classic kite-flying method in online novels. He shoots arrows from a distance and runs away when you catch up.
Then shoot again and run again, jumping back and forth.
Zhao Si really thought that this was how the Hu people fought.
"Where did you hear this?" Wang Li looked at Zhao Si with a strange expression.
This kind of tactic cannot be said to be invincible in the world, it can only be said to be broken at a touch.
The kite-flying style described by Zhao Si was quite explosive throughout the Spring and Autumn and Warring States periods.
