before transmissions had syncros, you would have to step on the clutch to take it out of gear, let off the clutch, than step on it again to put it back in gear. as opposed to steping on it, and going right from one gear to the next.
i have found it still comes in handy with wore out transmissions. i usualy have to double clutch my dd to get it into reverse.
or at least, i think thats right /forums/images/icons/smile.gif
It helps on a new large truck tranny which can be tough to shift. When down shifting, you want to go to neutral, bring the engine up to it approximate RPM in the lower gear, depress the clutch and shift into the next lower gear. Double clutching on the up shift slows the transmission to where the synchros have and easier job and don't fight you. With old "crash box" transmission it was a necessity and a special skill.
the sky is blue because blue light most easily scattered by the particles of air. the shorer the wavelegnth (purple is actually the shortest, but blue is up there) the easier it is scattered, so when the sun is high in the sky, most of the light (ie, orange, yellow, red, etc..) is not scattered. this is why, during a sunset, you can see different colors as the light you see has to pass through more and more of the atmosphere.
some food for thought: we see the sun after it has already set. ie, in the evening, when it is going down, we can see it after it is behind the earth. why? when light goes from one density of a material to another, it bends (this is called refraction). since the upper atmosphere is much colder (more dense) than the atmosphere at the surface of the earth, the suns light will refract off of the upper atmosphere, and bend around the curvature of the earth.
what does this have to do with clutches? i have no clue. but its cool none the less /forums/images/icons/smile.gif
Its somewhere around 9 minuets for the suns light to reach the earth if memmory serves me right. in the grand scheme of things, the speed of light is actually pretty slow.
alpha centauri, our closest neighboring star, is about 4 years away at the speed of light. which, acording to einstine, is the fastest anything can travel. kidna puts a damper on the whole space exploration thing... (yes i am aware that none of this information has any place in a mustang forum, but whatever...)
granny shifting is when you are jamming in first gear- full throttle and you back off momentarily on the accelerator simultaneously stabbing the clutch and shifting into second-be a wussie and do third the same way!REAL men don`t backoff on the throttle---just stab and grab--bang,bang,verrangggg-- oh #$%%^@!missed a gear!
look over and see your your buddies laughin`pointing fingers at ya!
