A Mid-level (Middle-aged) Office Worker’s Laid-Back Industrial Revolution in Another World

"So... if you add the inner diameter here to 180 degrees... I see... then use sin here... ah! I see!"

Tracy is taking Takeo's lecture and nodding back at the notes she took herself during the lecture.

"From here on out, I ask Mr. Tracey...

For example... I would assume that the load on the remaining two ends is 5 kg when the support tree is placed diagonally at 60 degrees and the force of 10 kg is applied to the end... what is the total load on this support tree itself?

Oh, I don't care about gravity or anything, it's just a theoretical idea.

Tracy and the ringtone face each other.

"Takeo, the answer is"

"Yes, Pana, let's keep our mouths shut.

Takeo stops because Pana is about to say the right answer.

"... Takeo, you're right. Do you understand?

"No, I don't know.

What do you care? I just invented a problem.

I'd think about it too if I had the paper, pencil and time.

Besides, I need to know if the members can withstand the surrender point of the material, the cross-sectional coefficients of the steel, etc...

You don't have a coefficient around... you don't even know how to calculate a number around it.

Do you want to do it, Mr. Tracy?

"Huh?... the... the director said... a cross sectional coefficient (?)?

"Yeah, it's necessary to calculate the intensity.

Mm-hmm... but hey... it's gonna be a hell of a hassle when you start doing this, and you're gonna make a trial and error from scratch, so it's gonna take a lot of time and...

I wonder if the test results of the materials coming from the Proprietary Bureau would be good if we were to do a simple calculation with the strength of the shield... if we increased the design safety rate would solve it?

Takeo thinks.

"Don't you need calculus, Takeo?

The ringtone is heard.

"To be precise, you need it.

But... it's hard to teach calculus, because I'm also a socialite and I don't use calculus at all... I can't lecture any more.

Was it in the book I photographed and brought from Wang Du... "

"Sure, I don't think I did.

Is it difficult to find out the details?

"It's hard as it stands.

The next time I go to the royal castle, I'll check with you if I get permission.

Even if you explain that to the Pannas... it will definitely take some time to understand.

Then can it only be done at 45, 30 or 60 degrees of the base angle now?

Plus √ 2 and √ 3 can be calculated at 1.414 and 1.732, so I think you should start designing with this for now.

"Is that good?

The ringtone is heard.

"Good or bad, in the first place, our aim is not to remember formulas or design difficult structures, but to generally check safety.

Finally, results are required quite a bit at a time not so far away.

I'm going to explain in Wang Du... but Mr. Tracy, I'll take you there.

We need to give a brief explanation at that time, but we need to show the easy numbers to understand, but 30, 45, 60 and 90 degrees will be easy to understand.

It will be a long time before detailed calculations are carried out, won't it?

Takeo arms up and twists his neck.

"Mm-hmm..."

The ringtone is thinking.

"In the meantime, I see that the director and Lord Suzune are thinking deeper.

I understand this triangular function first, while designing the shield, right?

I mean, make a thin sheet of iron, but... if you thin it to withstand the thickness used in full plates, it's natural to think you can't withstand it, right?

Tracy asks.

"It's obvious.

So... for example, I think we should try to incorporate trees to mitigate impact before or after hitting an iron plate.

... this way... you have the means to pinch a truss structure iron plate with a thinner plate than the tree you are using today.

Or if using wood in the first place doesn't prevent the bullet in the small gun, you may want to make a triple piece of truss structure that puts the iron plate in the surface + back + inside.

"I see... a truss structure between the surface and the back and...

By the way, Director... did you hit the iron plate to see how many mm it would hold?

"I didn't.

Ask the test platoon to use it during the live ammunition exercise.

"Then... we have to have an existing iron plate for the test, right?

"Right... the procedure would be the other way around.

First, the strength relative to thickness will come out roughly by checking with the actual product, making calculations for verification and support.

Plus, incorporating the truss structure into the shield assumes increased defense as a surface against the sword, the dispersion of the force due to the bullet breaking through the surface hitting the diagonal iron plate, which is the truss structure, and the reception on the back plate when breaking through there...

Well, for now, think of pinching the truss structure of the iron plate with a tree as the first.

If you can't prototype and prevent bullets, next time make a surface + back with an iron plate.

"Okay.

Tracy snorted.
