Do you notice? corrected!

When the car goes forward and backward, do you ever notice that there is a difference?
Yes indeed there is! Think for a while......... .. do you hear anything?

oh well when the car goes forward, there is no sound except the engine sound.. of course when you reverse your car, there will still be engine sound.. you can't reverse you car without the engine started, can you? so when you enter reverse gear and press the accelerator, you hear some sound which will eventually get louder and louder... yeap that's the difference.. so it has something to do with the gears.. the gears that convert the engine power to forward movement are called helical gears (auf deutsch schrägverzahnte Zahnräder), while for the backward movement the gears are called .spur gears (auf deutsch geradeverzahnte Zahnräder)

Spur gear

helical gear

i bet you are asking, WHY?

so this is the answer you looking for...
Specifically the way the teeth in the reverse gear are shaped. The forward gears in your transmission are helical shaped, meaning the individual teeth on the gear are curved rather than straight but reverse has straight cut teeth.

Why is straight noisier than helical? A helical gear's teeth are always in contact with the next gear thanks to their shape. Picture two straight gears moving very slowly. There's a split second that you'll see space between the teeth. The continuous tiny tapping of the gears remaking contact with each other creates the whine you hear. Since a helical gear has long, curved teeth, the point at which two gears meet is never out of contact, so no tiny taps, and no noise.

Quote of the day

"The world is full of thorns and pebbles. But, if we have to walk in spite of such obstacles, instead of trying to remove them, which is impossible, it is advisable to wear a pair of slippers and walk without harm."

Face problems with no fear. Obstacles in life are inevitable. On our way to achieve something we often faces a lot problems, critics, accusations, even people who influence us or sabotage us.. be brave and roar!!!!

Quote of the day

Out of sheer loneliness, people turn to alcohol either as a means towards socialization or as a way to drown and wash away their loneliness….

But alcohol can never wash away one’s troubles; it only worsens them, like feeding more fuel to fire

相机。梦想

自从参与Pat的Phototrip后,我深深地爱上了摄影,也很想很想为自己买一部dslr相机。以前没有多余钱,根本买不起DSLR相机。自从来到德国念书后,我省吃俭用,抽了一笔钱,终于买了一部DSLR相机。

有人曾经跟我说过, 不是每个人拥有畢卡索所用过的毛笔,就能画出拥有畢卡索的水准的作品。那时候的我觉得心如刀割。但是我却觉得我们凡事做事情,不需要顾虑到别人怎样看你,只要我们自己觉得那是对的,而且是我们能力范围里的事情,我们就应该去办我们所要办的事,勇于追求我们的梦想。
PS:功课做到一般突然间想起那个人对我说的话,那人的话已经深深地刻在我脑海里了,时时刻刻提醒我要努力学习,不断地学习和改善拍摄技巧。

Fantaghiro

Suddenly i thought of a movie that i fell in love with when i was little. The movie is called Fantaghiro. you watched before? it was aired in TV2 if i am not mistaken. It's like western version of Hua Mulan. After so many years.. let me count..ehhh.. 10++ years. sometimes the songs from the movie just came across my mind and i would hum it. the songs, though i don't understand a single word she sings but i like it, serene and calm i would feel when i listen to the songs..

here's the video. enjoy...

3rd OCT 2009 Mooncake Festival


远在德国的耀铭祝大家中秋节快乐!

PS:I used to carry lantern and walk around in my neighbourhood at night with my friends during Mooncake Festival. but nowadays i could hardly see any children walking at night because it's not safe anymore to walk at night especially for children due to the increasing crime rate in my neighbourhood, from snatch thief to orang minyak even murder cases..No kidding and i have been living there ever since i was born..
