Chapter 171: How Can Knowledge Be Measured by Money?
In the crowd, Qin Feng spoke confidently, “Do you think that there is no friction force on stationary objects?”
“Isn’t it true?” the crowd asked in unison.
Qin Feng waved his finger, “Wrong, absolutely wrong! What you see as stillness is merely the result of the friction force canceling out other forces. In reality, this force has always been present!”
“Take the example of the wine glass on a rough surface; it’s difficult to push because of the friction coefficient, leading to a significant friction force countering your pushing force! However, as long as your pushing force exceeds this friction force, the glass can still be moved! Do you understand what I’m saying?”
The crowd suddenly had a moment of enlightenment, “So that’s how it is.”
And Yuan Zhai, with more thoughts than these people, pondered, “In other words, sometimes the reason the wheel shape I choose can’t move heavy objects forward is due to excessive friction force.”
“If that’s the case, the wheel can only choose objects with a shape similar to a circle to reduce friction force. However, this brings back the original problem – when the vehicle moves on soft plains or mountainous terrain, the wheels are prone to sinking due to the pressure.”
To build a mobile city, various terrain factors must be considered. However, even after some guidance, Yuan Zhai, while understanding the reasons for failure, fell into a loop.
The people in the workshop fell into contemplation and confusion upon hearing this.
