Chapter 66 [Skillful Hands] Lydia
Hand fans, moving miniature steam boats, wooden flying wings, and many very delicate carriages and house models of equal proportions. Lynn even saw the prototype of a waterwheel in the center of the workshop.
This is a round wooden roulette with a diameter of about 1 meter. There is water flowing down from the reservoir above the workshop, which drives the roulette to rotate continuously and also drives the giant fan in front of it. Turning slowly, it provides a cool breeze for guests entering the workshop.
What an overkill...
Lynn shook his head. It is no problem to use this thing to irrigate the farmland, or even generate electricity, but Lydia only thought of using it to power the fan.
When Darren saw Lynn shaking his head and sighing, his heart immediately rose to his throat. Although these gadgets made by Lydia are very interesting, they certainly cannot be compared with the alchemy tools of wizards.
Fortunately, Lin En didn't mean to be a secret, and said directly.
"I'm not going to buy goods this time, but I'm going to ask you to make something according to the blueprint."
While speaking, Lynn picked up the model of the steamship and took a look at it. This model is very delicate, almost restored according to the same proportion, and every detail is specific.
From the chimney to the cabin to the hull, it is exactly the same as the steamships he saw at sea, except that there is an extra rope at the back of the cabin, which can drive the propeller below to rotate as long as it is pulled.
Almost instantly, Lin En guessed its principle, and a smile appeared on the corner of his mouth, and asked again.
"I heard that Lydia's hands are very dexterous, and she can always make items exactly as required. Is that true?"
"Of course, I dare say that there is no one better than Lydia in this port of Iyeta!" Darren said confidently, even many wizards have seen Lydia's small work. After the gadget is full of praise, it has the name of [Skillful Hand].
"Is she in the workshop now?" Lynn put the model aside, "I want to see for myself whether she can meet my requirements."
"No problem, Lydia is working in the backyard right now...I'll take you to find her!" Darren quickly jumped off the stool, hung up the rest sign, and opened the door to the backyard of the workshop.
Lynn walked in with Darren, and saw the large aircraft he had seen before at a glance, and the halfling Lydia he was looking for was standing under the aircraft at the moment, holding a large aircraft half her body in his hand. Such a long hammer smashed several thick iron nails into the wings of the aircraft.
After finishing all this, Lydia wiped the sweat from her head, and then tugged the wings vigorously with her hands. The connection is very strong, but the stability is still a little bit worse, which is why the aircraft is a little bit weaker after landing. The reason why the parts fell apart directly.
The halfling girl didn't notice the two people who entered the door at all, her brows were slightly frowned, and her robe was already covered with dust, but she didn't care at all, her mind was full of how to improve this aircraft.
At this moment, Lynn's voice suddenly sounded.
"Since the quadrilateral is not stable enough, why not try to add a beam at the diagonally opposite corner and transform it into two triangle structures?"
Lydia froze for a moment, then turned her head immediately, only to find Darren and Lynn standing beside her.
"Master Wizard?" The halfling girl shouted in surprise, and she also quickly recognized Lynn who had met briefly in the square before.
"You can try it first!" Lynn pointed to the wings of the aircraft and said with a smile.
Lydia was not stage-frightened either. Even when she pulled up her sleeves, she lifted a board of suitable size with both hands, placed it on the opposite corners of the wings, and picked up the hammer and nails, clanging knocking on and on.
What a lot of strength...
Lin En was very surprised to see Lydia, who was only about 1.3 meters tall, easily lifted the wooden plank that was bigger than herself.
This doesn't conform to biology at all... Lin En looked at the halfling girl's arm, which could barely be considered "strong", and couldn't help complaining in his heart, and then ordered the other party to build brackets around the aircraft to strengthen it The overall structure has removed many unnecessary structures, reducing the weight of the body itself.
Darren also hurried forward to help. After working for a long time, the whole aircraft took on a new look. The wide wings on both sides were connected with the fuselage in a triangular structure. Lydia put her hands on the wings and shook them violently for a few times Then he tapped it with a hammer again, but there was no slight deformation.
"This is simply... wonderful!" The joy on Lydia's face was almost overflowing, and then she turned her head to look at Lynn, and asked in confusion. "But why?"
She also noticed this difference when making those models on weekdays, but she didn't understand why it happened.
"Because the three sides of the triangle are connected end to end, it forms a very stable structure. You only need to do a force analysis to know..." Lynn took a few wooden sticks and assembled them into a triangle. Quadrilaterals and pentagons, and then drag any side and any corner of them to demonstrate the force changes of these polygons.
Lydia was sitting on the wing of the aircraft, her bright eyes were fixed on the wooden stick in Lynn's hand, like a student listening to a class, she forgot for a moment that Lynn in front of her was only meeting her for the second time That's all.
However, Lynn's course is not so easy to understand. There is a demonstration of wooden bars in the first half, and Lydia can understand a little bit. After that, she is confused about the center of gravity, wind resistance, and friction.
Only two conclusions were drawn.
First, the wizard in front of him is very knowledgeable and knows a lot of things. Second, whether the aircraft can fly may be related to these forces...
After talking for a while, Lynn pouted, the halfling girl immediately understood, jumped off the wing, ran into the room with a thud, fetched a kettle and poured a glass of water, and handed it to Lynn's hand Come on, then looked at the other party eagerly, and asked.
"Master Wizard, can this aircraft fly now?"
"If you just want to stay in the sky for a while, that's no problem, but if you mean flying freely in the sky, I'm afraid not!" Lynn shook his head, "The power of this aircraft is too poor, and the shape and structure It's not very fluid dynamic either..."
The halfling girl looked bewildered, she could barely understand the dynamics, but what is fluid mechanics?
In just half an hour, I heard many high-end words that I had never heard before. Lydia looked pitiful like a kitten that saw a fluffy ball but couldn't scratch it.
"Master Wizard?" Darren on the side was a little worried, and couldn't help but interrupted. Although he also wanted to hear this knowledge, he knew a truth, all knowledge is very precious in the land of wizards!
Lin En seemed to have just reacted, with a smile on the corner of his mouth. "Sorry, this is a professional error..."
"I haven't introduced yet, my name is Lynn, and I'm the new Olympiad mathematics professor at Iyeta College!"
"Is that the rumored Omaha mathematics professor who frightened a student into fainting on the first day of class?" Darren exclaimed.
The corner of Lynn's mouth twitched involuntarily, and he looked at Darren very'kindly'.
If you can't speak, you'd better shut up!
