Mohs hardness.
It is a standard for representing the hardness of minerals.
A Mohs hardness of 1 indicates that an object is very soft, like talc, even softer than human skin.
As for the concept of 2.5... it's roughly equivalent to a fingernail or a block of ice at minus 5 degrees.
A rock of this hardness can also be broken by adults with sharp tools.
The hardest natural substance is diamond, which is the standard 10.
However, currently, artificially synthesized polycrystalline diamond nanorods on Earth have exceeded a hardness of 10, making it the hardest material currently available dostically.
As for an upholder nad Bosang... 0.0001, perhaps?
In a certain sense.
In this era where trends update at such a quick pace, it's actually not easy for him to create a harder than Bo all on his own.
The sight returns to the original place.
Once the hardness of the stones in the groove was understood, the remaining problem was quite simple.
Pan Guansheng and others introduced three more guided robots, each connected by several polyethylene fiber ropes with high molecular weight.
Then, under the guidance of the control panel, they moved to the left and right sides of the ice coffin along the boundary of the groove.
Counting the robot already inside the groove, there were exactly two robots on each side.
The task for these robots was simple:
Use pulse drills to make four curved holes 3 centiters from the bottom of the ice coffin. The holes are near the top and bottom sides of the frozen coffin, far from the center.
After all, it was judged that there might be an opening below the ice coffin,
Even with the ice coffin covering it, the wind was level four; once the ice coffin was moved aside, the wind would reach at least level six, wouldn't it?
Once the holes are opened, polyethylene fiber ropes with high molecular weight will pass through the holes, then directly pull the ice coffin up.
This approach is a bit more complicated than using manpower to get into the pit, but it corresponds to lower risks—who knows if any harmful substances would erupt from that opening?
If the robot is destroyed, then so be it; manpower doesn't have a concept like margin for error.
Once ready, the machines start.
Bzzzz—
Soon.
The four pulse drills burst forth.
A pulse drill is a drilling device that erged a few years ago, not widely popularized.
It specifically targets stones with a Mohs hardness of less than 3.5, having certain limitations in use.
But that a thing with obvious limitations was pursued by front-end R&D indicates it has certain exceptional qualities.
And indeed, it does.
This thing is fascinating—everyone's seen the tape asure akin to what you'd find on a construction site, right?
Pulse drilling is sowhat similar, where the drill bit is made of high-strength elastic tal, usually retracted into the left containnt area of the guided robot.
After leaving the equipnt, the externally linked pulse current and neon gas (located outside the cave) provide mory feedback.
Finally, it becos thicker and harder, thrusting forward with a burst of energy.
Typically, a guide robot with a diater of fifty centiters has a soil detection chip on the right, while most of the left area is taken up by drill bits, capable of drilling a passage with a maximum length of two ters and a diater of 6 centiters.
The long-term prospects for such robots primarily lie in post-disaster rescue in towns, which is quite aningful:
Pulse vibrations can avoid secondary collapses to the greatest extent, while the drilled passageways can deliver oxygen or liquid food.
Likewise, in disaster entrapnts, so people may simply lack oxygen, others may lack water, and so may sustain life-threatening injuries—even though the forr two are described as "simply", a lack of oxygen and water may lead to death even earlier than for those with severe injuries.
This breakout guide robot targets the forr condition, thereby buying ti to rescue critically injured individuals.
Currently, the dostic pulse drill can drill a passage of up to eight ters long, while the machine's diater is rely 40 centiters, with a height of 1.5 ters wide.
Of course.
Due to the drill bit being flat when internal, the hardness of the drill bit is relatively limited.
Thus, drilling into high-strength materials is still quite difficult, with a ceiling at substances of shell-like strength.
The 17-year procurent of disaster relief supplies in Star City included 45 of these guided robots.
In summary, this is sothing that could potentially save many lives in the future.
The sight once again returns to the original place.
Below the groove, next to the ice coffin.
As pulse currents and neon gas are injected.
The mory tal rapidly underwent deformation; the elongated, thickened, and hardened drill bit beca steadier.
Soon.
The four underground holes near the upper and lower ends of the ice coffin were opened.
Although the distance from the ground to the hole is five centiters, the bottom substrate is not all hard rock; at least 70% is soil.
Thus, the five-centiter soil blockage for the hoisting operation is almost a trivial little indulgence easily overco.
Then, under the guidance of magnetic adsorption equipnt, four high-molecular weight polyethylene fiber ropes passed through the holes.
They then appeared at the other end, and were pulled up.
Eventually forming a horizontal shape resembling a 凵, with the uppermost end connected to multiple-stage compression cryogenic pulling units.
Once everything is ready.
Lu Chaoyang waved his hand:
"Coffin lift!"
Rumble——
As soon as Pan Guansheng pressed the button, the cryogenic puller let out a low rumbling sound:
This polar-exclusive equipnt, while robust, forsakes subtlety, hence the noise is still not low.
However, Lu Chaoyang was not disturbed by these noises.
At this ti, his eyes were fixed on the ice coffin, paying close attention to every tiny change.
According to the command center's plan.
The maximum weight that this set of A-plan equipnt can lift is 8.6 tons, also the limit for lifting without affecting the cave layout.
If the ice coffin exceeds this weight, damaging the cave isn't likely, but it might have to break so loose soil, providing an operational environnt for advanced equipnt.
If increasing to 20 tons still doesn't work, then other plans ntioned above have to be activated.
At that ti, it may inflict irreparable damage to the colorful fruit inside the cave, possibly even leading to the complete demise of the vines.
Undoubtedly, this would belong to the approach of harming a thousand enemies while losing... not quite eight hundred, but at least losing three hundred itself.
Second by second passed by.
Finally.
When the equipnt was operating for about fifteen seconds, the ice coffin showed signs of being moved.
At this mont, the number displayed on the traction screen was...
3.1 tons!
That being 40% of the load!
After that, Pan Guansheng steadily controlled the console, calmly continuing to increase the traction.
When the number reached 5.4 tons, the ice coffin slowly started to levitate!
After over ten minutes.
The ice coffin finally rose to the ground, as Su Bai and others swiftly stepped forward to carry out the finishing process.
Upon seeing this, Lu Chaoyang lightly exhaled:
His mission was finally complete.
Then his peripheral vision caught a glimpse of the nearby Su Bai and others removing the ropes.
Suddenly.
An idea flashed across his mind, suggesting another possibility.
He held a piece of paper in his hand and quickly dashed to the edge of the ice coffin.
Then gently placed the paper over the ice coffin.
The paper, under the influence of gravity, first lazily drooped down, but in less than a few seconds...
A slight sound was heard:
The front part of the drooping paper was gently trembling, emitting a rustling sound.
In other words.....
The ice coffin.....
Was actually the wind source!
........
Note:
As said before, after completing it, I will release it, but won't guarantee a specific amount daily, though an average of 9000 should be there.
Losing the intelligent push, there are currently only two traction charts left, the monthly ticket list and the bestseller list, ask for monthly votes!
