发帖数: 142 | 1 I will use bolt to describe the thread. nuts are much easier and simpler
since they just match on bolt.
first, the thread pitch. metric uses milimeters, such as 1.0mm, 1.25mm.
fundamental property of thread. SAE uses fractional inch, such as 1/8,
5/16, etc.
second, the same pitch could have different diameter. the common sizes are
6x1.0mm, 8x1.25mm, 10x1.25mm, 12x1.5mm. the diameter refer to internal
size. add 4-6 for the size in socket. eg...6x1.0mm in most cases,
corresponds to 10mm small bolt |

发帖数: 163 | 2 I don't know about the rate for Nissan.
if it more expensive on the pressure hose, usually it require replace of the
hose itself.
if on the return line, then $180 is too expensive. the return line if leaks
at a clamp, sometimes trimming rubber hose by a few milimeters and then
reclamping it will stop the leak. |

拉登 语录
We have spent a lot of time on this particular issue actually. The tough
part is that this question is dependent on assumptions. i.e, the amount and
frequency of steering. It's just a matter of balancing the benefit during
stable steering versus the penalty during steering. For ironman athletes
with extended elbow time, steering tends to be very stable. We spent a lot
of time watching race videos on this. ... 阅读全帖 |

发帖数: 2428 | 6 Acutally the 'simple mechanics' are not quite simple. Before I start doing
this project, I hold the same kind of view. However, when I was at it, I
found out it is totally different. Sometime the board line between feasible
to impossible is much less than a milimeter, let along the torlerance that
governing the reliability of the functions.
Being academic or not is not crutial. What I learned in the school has much
less effect than what I learned from technitian's that I have fortune to

发帖数: 17096 | 7 球印的问题多了
joker和melzer的比赛，melzer给裁判划了个错误的球印，裁判居然也信了。慢镜和鹰
眼显示球in
还有球员会在落地之后用脚抹去球印
另外最大的问题就是球印的错误率比鹰眼高了至少十倍，土场的地软，球砸下去又会滑
出，加上底线比土场高1个milimeter，球擦到边线的球印也可能是在线外。这个时候就
看怎么定义了。
如果想保证完全公平，就需要鹰眼，鹰眼是假设球场完全flat，边线和地面没有误差，
而且不考虑土的厚度和软性。 |
