"Speed up or ......?"

Jin thought for a moment about how to answer the question from Kondak, Marikka's grandson and disciple,

"I think you know about the air resistance, the weight of the aircraft, and the propulsion ......."

"Yes, of course.

"But you still don't know how to reduce them, do you?"

"That's right."

It was almost as Jin had predicted. The Nordic Federation is well educated, and in terms of general education, it far surpasses the countries of the Laurentian Continent.

That is, beyond that.

(I don't know that much about it myself, you know...)

"<> have high air resistance in principle, as you can see. However, there may be room for improvement by changing the shape of the wings. ......"

Weight is material and structure, propulsion is efficiency and power.

Jin explained these generalities as well.

"Thank you very much."

"The last one is entry number 10, Lerstner from <>.

She is a female engineer, and Jin had seen her in Marikka's workshop .......

"<>. Is there any harm in making it too rigid?　I'm sorry, but I don't have enough time to experiment anymore."

"Fuun ......"

The question and answer session so far had raised quite a few questions and hints for their solutions, so the questions tended to become more technical the later they were asked, but Jin didn't expect this.

"First of all, general remarks. Stiffness is important, but too much stiffness makes it brittle. Also, when the load exceeds the limit, it tends to be destroyed at once. I think that is dangerous.

Hard things break. Soft things bend. It is difficult to find this balance, and it is the engineer's skill to determine it," Jin said.

"......"

"One way to prevent this is to provide adequate elasticity and toughness, or to use composite materials. Also, the strength will vary depending on the structure."

He refers to light and strong structures such as trusses and honeycomb structures.

"Then there are the properties. Something hard and brittle is weak in tension and bending, but strong in compression.

Concrete is a good example of this, and the design includes a lot of reinforcing steel bars in the areas where tensile load is applied.

I hope these tips will help you to be creative."

"Thank you very much."

This concludes the questions from the 10 participating teams.

This shows that they are all technical clans.

Moreover, most of them are related to Marikka, i.e., disciples, grand-disciples, or colleagues.

Jin thought that this might be natural since this is the <>.

Finally, when asked if there were any general questions, Zion's hand went up.

"Well, I'll start with one.

Then Zion started his question with a preface.

"Have you thought of a model performance?

In other words, he wants to see the blow floaters that Jin has made.

"I'm not thinking about it this time, but ......"

Jin says, "I'm not thinking about it this time, but I'd love to see it!

"I'd love to see it!

Many of them said, "I'd love to see it!

You see," he said. As one of the organizers, you should think about it.

Jin said to Zion,

Jin replied, "Okay. I will think positively. I'll bring < to ...... at the worst.

Jin replied, "I'll think positively.

Jin returned to Horai Island that evening, although he unexpectedly lost some time in the .

Everyone knew what had happened from what the old man had told them,

They all knew what had happened and thanked Jin for his hard work.

They thanked Jin for his hard work.

Everyone knew what Jin had done, but after dinner, Jin explained what he felt and how he felt.

"I see, so technical people are growing up in the Nordic Federation!"

Reinhardt looked pleased.

"I am glad to see that my students are motivated.

Marikka also looks happy.

Here comes Jin,

"I'm thinking about the trophy for the Marikka Cup, but I'm not sure about the statue of Marikka when she was young.

"What?

"Oh, that's nice."

"I think it's good."

"I think it's a good idea."

"Yes, I agree."

Everyone seemed to agree, except for a few responses.

"In my world, too, there was a design of a goddess of victory holding a laurel wreath above her head to wear as a sign of victory," he said.

"Oh, I see."

"Huh. ......."

Marikka is blushing, and Jin says, "Well, it's small,

"Well, you won't recognize him at first because he's so small.

Marikka blushed and Jin followed up by saying, "Well, you're so small, you won't know who he is.

"......"

She still looked down,

"Well, let's give it a try.

and asked Reiko to bring a silver nugget to the table. Then, he said,

"<>"

He made a statue of Marikka at once.

Instead of holding the crown of laurel above her head, she lifts it to the height of her chest.

"Oh!

"That's a real gin, isn't it?"

"Huh?

"You're right, if you don't look closely, you can't tell who it is.

That's what I was trying to make.

The outline of the figure was blurred so well that, although we could tell that it was a woman, we could not tell who she was unless we knew her to be so.

She was dressed in a toga, or loose-fitting cloth, like those worn by the gods of Greek or Roman mythology, and her body lines were barely visible.

Marcia complained, "I was in a bathing suit when I was here.

Marcia complained, "This is not a figure,

But she brushed it off, saying, "This is not a figure.

But she let it slide, saying, "This is not a figure.

"So, what if we put it on an ebony or purple ebony base?

"Well, don't you have any red wood?

Reinhardt said,

"Yes," said Reinhardt. <. You can sometimes find it on Horai Island.

"I'm sure there were some samples.

Reiko brought a wood sample that Jin had never seen before.

It was a file of several wooden boards processed to the size of a business card, which showed the texture of the wood. It seems that this was also made by the former Jin.

"Oh, this is it."

was indeed wood. It is close to the tree known as in modern Japan.

"I'll take this one. What about the stock?"

Enough for the base of the trophy.

Okay.

Thus, the trophy for the winner of the Marikka Cup was completed.
