2. Sliding friction
F
=
μ* FN
the sliding friction is always smaller than the maximum static friction. It consists of the pressure FN perpendicular to the friction surface and the sliding friction coefficient μ It is independent of the relative velocity and area between sliding surfaces. The friction coefficient is determined by the material, roughness and (possibly) lubricant of the sliding surface
[2]
rolling friction
If an object rolls on a plane, it will be subject to rolling friction. If the friction between the rolling object and the plane is equal to the resultant force of all other forces exerted on the object, then its motion is a pure rolling motion, in which there is no sliding part. Rolling friction is the friction that the contact surface changes all the time when the object is rolling. It's essentially static friction. The softer the contact surface and the greater the shape change, the greater the rolling friction. Generally, the rolling friction force between objects is far less than the sliding friction force. Rolling bearings are widely used in transportation and machinery manufacturing instry to rece friction
[2]
for example, the friction of the driving wheel of a train is the driving force to push the train forward. The static friction of the passive wheel is the rolling friction that hinders the train from moving forward
rolling friction
If rolling motion and sliding motion exist at the same time, then this kind of mixed friction is also called rolling friction
rotational friction
the friction proced by a ball rotating along its axis perpendicular to a plane is called rotational friction, which is related to the moment t of rotational motion:
n = frac {t} {f}_ N}incm

3. 1. With more experience, the proction time will be reced, and the quantity will increase.
2. Go to the bank, not every version has, I remember the Renaissance has...
3. It's easy... Don't cheat you... See how you play. The original version introces you to play hooligans, and other versions play people's livelihood...
4. Only go to the wild, or kill a building in the city.
5, Price, purpose, weapons are the most popular

4. Improve your original wooden house, hire two thugs, the three of you go to the mine together, if you are lucky, you can fight all the time without being interfered. If someone interferes, you can kill him directly, fight the mine to red blood (the process is slow, please be patient), then you can occupy it (send the thugs to occupy it), and the mine is yours. This is the way I use. I'm not happy with all my trials. The mine is also the most profitable. Please believe me...
5. It's a pity that if the original price is really cost-effective, the performance is mainly a victory in the manufacturing process, from 12NM to 8nm, there are also improvements in the first generation of light chasing and dsll technology. After all, the first crab eater is generally not perfect. Rtx2000 is an experimental and transitional proct, and rtx3000 is much more mature
unfortunately, it's not made by TSMC, but by Samsung, TSMC's proction capacity is totally insufficient
otherwise, it can achieve 7Nm, with higher performance and stability estimation

6. According to the current news, only the new Titan RTX 3090 supports firefight.
