“The four basic mechanical principles are Free Body Diagram, Equilibrium of Forces, Displacement Compatibility, and Stress-Strain or Force to Displacement Relations.” Shi Tian answered the question in a textbook perfect form.
However, Isaac Aaronax wasn’t impressed by the answer and lamented.
“Nathan, I’m not just asking what the four basic mechanical principles are, but how they are utilized.” He said calmly.
“I never said I was finished, Master Isaac.” Shi Tian smiled calmly and placed his left hand on his right shoulder.
A few seconds later, Shi Tian detached the mechanical right arm. Since the mechanical right arm was linked with his body, it would only take a thought process to detach the arm away.
He then placed the mechanical right arm on the desk and began explaining the first principle.
“When I first came here requesting for a mechanical right arm, you took my measurement. That was when you began the process of the Free Body Diagram. Not only were you measuring my body proportion to get the perfect measurement, you were also deducing the appropriate reaction or internal force that must be added in the right arm to match my physique.” Shi Tian explained.
“Go on,” Isaac Aaronax said, staring at him, seemingly curious what he was going to do next.
Shi Tian nodded his head, picked up the mechanical right arm and balanced it perfectly with his left palm.
“The equilibrium of force principle was utilized here in which the right arm should be in the same dimension, magnitude, and proportion of my left arm. If any of it was to be slightly different, then my body would have been in great discomfort, and possibly even having my movement restricted or constrained.” He calmly explained, before attaching the mechanical right arm back.
After having it equipped for quite a while, Shi Tian was a bit uncomfortable to suddenly have it detached from him. Nevertheless, it was needed to demonstrate his explanation and let Isaac Aaronax know that he wasn’t some greenhorn.
“Then what about the Displacement Compatibility and the Stress Strain Relations principles?” Isaac Aaronax asked.
“Do I even need to explain further?” Shi Tian smirked and walked toward the machinery that Isaac Aaronax had used to take his measurement and equipped the mechanical right arm for him.
“Technologies have been advanced to an unimaginary rate, so the last two principles were done by this machinery, saving a lot of time.”
“Heh, very well then. I suppose you do have the knowledge of being a basic apprentice.” Isaac Aaroanx chuckled softly and nodded his head.
Truthfully, he was already pleased to hear the first two explanations from Shi Tian. It was adequate but also not so far-fetched to bore him out.
He then walked up and touched the machinery in a nostalgic manner.
“Indeed, technologies have been improved and are the only reason why humanity is still surviving. Just this simple machinery was able to help save time for mechanics, but that doesn’t mean being a mechanic was an easy path.” Isaac Aaronax said bitterly.
He turned toward Shi Tian and asked solemnly, “Why do you think mechanics aren’t so common and why aren’t there many people willing to take on this path?”
“The answer is quite simple, Master Isaac. It’s the lack of resources.” Shi Tian smiled.
Isaac Aaronax nodded his head. “Correct, the lack of resources is the greatest setback of anyone striving on the path of mechanics. Mechanics is the one class that requires a ton of resources to even achieve something compared to the rest.”
It was a given that metals materials and other machinery required for a mechanic to use are limited. There was a reason why Gearits City contained so few mechanic shops, and even within some mechanic shops, the qualities are extremely subpar.
The metals materials are difficult to obtain, since not all metals are usable. Not to mention, even if there were an abundant amount of metals available, the qualities of them wouldn’t be satisfactory for them.
And if there were great metal materials, it would already be taken by those on the top hierarchy.
How could any ordinary mechanic get their hands on high quality materials?
“Compared to the infinite amount of Magicules in this world, the other classes definitely have it easier. Magicules are everywhere and no one could monopolize them for self use.” Isaac Aaronax sighed exasperatedly.
Shi Tian remained silent, but inwardly, he understood Isaac Aaronax’s pain. Mechanics is truly the most expensive class to strive for and have any achievement on.
But what could he do?
He had no talent in manipulating the Magicules in this world whatsoever. Not everyone was blessed to have an affinity with Magicules.
The Berserker Class, Magus Class, Esper Class, and even the mysterious Clairvoyant Class all use some form of Magicules. Only the Mechanic Class does not need any Magicules.
When Shi Tian had learned of the world containing a substance known as Magicule, he attempted to study and manipulate it, only to no avail.
He couldn’t even sense Magicule, much less even be able to utilize them. Thus, he was only left with the option of becoming a Mechanic if he wanted to become stronger.
“Alright, let’s not get depressed over this matter. We might not be capable of manipulating the Magicules, but we aren’t to be underestimated either. A capable Mechanic could craft something that is able to contend against those who could utilize Magicules.” Isaac Aaronax lifted his sleeves and said confidently. 𝐞𝗼𝐯𝐞𝗹.𝗰𝗼𝗺
Shi Tian smiled and nodded his head in agreement. They might not be able to utilize Magicules, but they could craft something that could mimic it.
Just the powerful Light Beam that Isaac Aaronax had demonstrated previously was evident enough.
Now that he had been exposed to the existence of Magicules, Shi Tian came to realize that the Light Beam was not only formed by a combustion of forces, but also from the utilization of Magicules.
“I’ll be in your guidance, Master Isaac. We shall let the world know not to underestimate a Mechanic.”
