"Is this a tower crane?"
Scorpion watched as Shisō was installing the crane arm, and then manipulated the Crow puppet to go over and help tighten the screws.
In response to Scorpion's question, Mukai simply used a model to give Scorpion a live explanation of lever arm and torque:
Do you remember the Chakra Threads pathways when you were piloting the Mountain God Mecha?
It works on a similar principle to the energy storage device that initially powered our mechs.
Now let's use this tower crane model to more clearly illustrate the relationship between these forces.
Mukai pointed to the origami crane model and continued:
"For your tower crane used to lift heavy objects, the tower body is the core, and the boom is the key."
Isn't this just like your Chakra Threads and your ability to control targets?
Previously, besides the pulling of Chakra Threads, traditional puppeteers tried to minimize the weight of their puppets, which affected their puppeteers' efficiency in controlling them.
The puppets we previously incorporated power units into, such as the Mountain God Mecha, alleviated the pressure on the Chakra Threads to some extent.
However, the traditional method of using Chakra Threads to lift the puppet is the least efficient.
This is equivalent to using a long pole to lift a heavy object from a distance, which would be extremely difficult.
This involves the lever arm; the horizontal distance from the lifting point of the tower crane to the tower body is the lever arm.
In your daily Chakra Threads, the effective distance from a fixed point to the target is also the lever arm.
When the line is perpendicular to the direction of the force applied to the object, the lever arm is the longest, and the effort required is the least.
You can feel the difference between directly controlling a puppet with Chakra Threads and remotely controlling it with control threads.
Sasori nodded. As a genius puppeteer, he had only focused on the creation of puppets before, and hadn't really thought about the efficiency of the Chakra Threads.
In the original timeline, he created Human Puppet with a certain degree of autonomy, so he naturally didn't need to consider these things.
Now that Mukai has reversed Scorpion's fate, he naturally needs to make up for Scorpion's loss of power in other ways.
What could be more effective than fundamental mechanics knowledge?
Mukai continued:
"Torque is force multiplied by lever arm; the tower crane's load multiplied by the boom length equals the torque."
If this value is exceeded, the tower crane will tip over.
For you, it's Chakra pull multiplied by the effective lever arm.
If you want to use Chakra Threads to overturn a boulder
What's needed isn't just the skill to train one's own Chakra Threads, but the ability to lengthen the lever arm.
If you want to quickly fine-tune the puppet's posture and movements, you can shorten the lever arm, making the Chakra Threads travel a shorter distance.
Sasori thoughtfully manipulated the puppet with Chakra Threads, and suddenly understood.
His eyes gleamed with a thirst for knowledge as he continued to ask:
"So what exactly are the uses of the movable pulleys and fixed pulleys you mentioned?"
Mukai felt like she was tutoring students in class.
This student, still a puppet genius named Scorpion, continued with a great sense of accomplishment:
"This application can maximize the specific applications of Chakra Threads."
You see, the fixed pulley here on the tower crane is a stationary pulley. Its function is only to change the direction of the force; it does not save effort.
When you use Chakra Threads, you can change the direction of the object you are pulling by looping the thread around a fixed fulcrum such as a tree trunk or rock and pulling the other end.
This is also a disguised application of fixed pulleys.
It's especially useful when you want to move the puppet around obstacles or quickly move it behind an enemy.
The crane hook uses a movable pulley that moves with the load, saving half the effort, but requiring the steel cable to travel a longer distance.
In practical application, it's like using Chakra Threads to control Mountain God Mecha to dig, sacrificing travel distance to gain greater power.
Mukai took out the planetary gear set of the tower crane boom and said meaningfully:
"The principle is the same as this planetary gear set, using a small gear to drive a large gear, sacrificing speed to obtain high torque."
Using a large gear to drive a small gear requires more force, but it can achieve extremely high speeds for the small gear.
In terms of strength, it has always been fair.
Scorpion reached out and felt the fixed pulley and the movable pulley, as well as the different effects of the cable travel and the planetary gears.
He took the models and ran straight back to the workshop.
Mukai didn't stop him; for a genius like Scorpion, many things are easy to grasp.
Like a pleased teacher, he clapped his hands in satisfaction and continued to direct the installation of the tower crane.
With the help of a rudimentary intelligent Crow puppet that can fly, and the incredibly powerful Shisō, the seemingly crude tower crane was successfully assembled.
Looking at the cement slurry that required more than ten small trucks to load,
The fact that this steel contraption easily grabbed the wall under construction drew gasps of surprise.
Even Little Shira was clapping and cheering from the sidelines.
As Shisō landed steadily, he looked at the mechanical creation and sighed:
" Mukai, this tower crane and heavy-duty truck only consume electricity."
That would allow me to obtain the power that I would need to activate the Seven Heavens Breathing Method or the Eight Gates Released Formation.
Is there still a use for Taijutsu ninjas?
Mukai ruffled Shira's hair and said calmly:
"The purpose of these tools is simply to amplify the power of ordinary people."
The same axe can be used by an ordinary person to chop firewood.
And once you activate the Seven Heavens Breathing Method and the Eight Gates Released Formation, you can even split mountains in two!
Whether a tool is powerful, like the power of Ninjutsu, depends on who is using it.
A simple Ninjutsu, performed by an ordinary ninja, might not even be enough to kill a person.
When wielded by Madara Uchiha and Hashirama Senju back then, it possessed earth-shattering power.
Mechs and Ninjutsu are merely tools for us to become stronger in this world.
When Taijutsu are honed to a higher level, combined with a more powerful mecha, the unleashed power far exceeds imagination!
The Taijutsu you and Shira have practiced will never be outdated!
Once our school is running smoothly, you need to select more children who are skilled in Taijutsu.
The Seven Heavens Breathing Method and the Eight Gates Released Formation are both tools for becoming stronger.
But don't treat them as disposable items.
I don't need you to sacrifice yourselves for a fleeting moment of brilliance.
I need you to teach them how to amplify this controllable power through martial arts and mechs.
Is it possible?
Before Shisō could answer, Xiao Shira stood up straight, pounding her chest with her fist and shouting:
"It's possible!"
His youthful voice radiated confidence.
Shisō patted Shira's head affectionately, then clenched his fist and pounded his chest, making a loud thud.
"One promise, seven o'clock sasa gailu (loyalty to the death)"
Mukai also clenched his fist and pounded his chest in response:
I will definitely not let you down!
Let's become stronger together and use our power to achieve true peace in the Shinobi World!
mutual encouragement!"
With the commissioning of the second truck and the fourth tower crane, the construction of the entire Oasis Fortress accelerated considerably.
The city wall that has now been poured is already over two meters high.
When the cement transport is no longer needed, these trucks will continue to plow and cultivate the land.
The workshop currently has limited steel reserves, so priority must be given to fortress construction; the construction of other vehicles must be temporarily suspended.
Mukai has been working non-stop on electrolytic smelting of steel these past few days, and he hasn't even had time to process the slag containing Chakra Metal.
He was about to head back to Sunagakure to participate in the Shukaku Trial.
