Aug got another 'GNO' ah?

 

wat's GNO?

[0re0]

Blue.. read below...

 

 

 

 

 

 

2 more days!!! WOOHOO!!!!!!

 

 

 

Ya... and after that, its another 40 years... hahaha

well...if it's mentioned by kelvin i dun tink is any of the above haha

[clair]

Eh.. i tot u can eat 5 seeds of D**** already?

 

Eat can La.. But not the smell lor.. Some more the smell now "Permanent resident" in the van lor...

[draught]

Now prata good to sell mah..

 

There's a new prata shop at JK.. '08 Prata Tong'.. Heard reviews that the food there is nice

 

So tonight dinner there?

[clair]

So tonight dinner there?

 

Now also haven lunch time.. think of dinner liao...

[fabian]

Anyone interested in this?

 

Yummy yummy!

 

Me interested!!

 

bUT mELAKA??

[fabian]

hey guys, faith was finally delivered to bikeworkz y'day. see liao heartpain...

gOSH Hope rider is fine...

By the way, this incident is not the one at upper thomson right?The one regarding a vehicle making a u-turn causing a female rider to knock against it.

[PreluDe]

finally my bike is done,but too bad cannot ride yet cos the bike seem to be quite heavy perhaps need more time to rest again before taking up my bike again

[fabian]

i look up into my text book and it gave me the formula of the torque ma..

 

You really went thru the troubles..

'cept for the heartache, the rider's fine and dandy...

calling the double digit rider.

when can we take family photo?

 

manzz dun mind. once got any idea, drop me a msn msg. thanks

[PreluDe]

just came back from swimming therapy training ,self pratice . tommorrow will be a new head start , working liao no more CBL

Huh?!?

 

Where did Nitekidz go?

Chao, hope this ans ur question.. And nO.. I do not type these chim chim stuff out myself

 

 

The gear ratio is the relationship between the number of teeth on two gears that are meshed or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt.

 

http://upload.wikimedia.org/wikipedia/commons/thumb/4/42/Gears_large.jpg/200px-Gears_large.jpg

 

In the picture above, the smaller gear has thirteen teeth, while the second, larger gear has twenty-one teeth. The gear ratio is therefore 13/21 or 1/1.62 (also written as 1:1.62).

 

The first number in the ratio is usually the gear that power is applied to. In an automobile the first number is the gear receiving power from the engine.

 

This means that for every one revolution of the smaller gear, the larger gear has made 1/1.62, or 0.62, revolutions. In practical terms, the larger gear turns more slowly.

 

Suppose the largest gear in the picture has 42 teeth, the gear ratio between the second and third gear then is; 21/42 = 1/2 and for every revolution of the smallest gear the largest gear has only turned 0.62/2 = 0.31 revolution, a total reduction of around 1:3.

 

Since the number of teeth is also proportional to the circumference of the gear wheel (the bigger the wheel the more teeth it has) the gear ratio can also be expressed as the relationship between the circumferences of both wheels (where d is the diameter of the smaller wheel and D is the diameter of the larger wheel):

Since the diameter is equal to twice the radius;

 

http://upload.wikimedia.org/math/4/0/e/40e8754bbbb161c0df4968bfdd6558ae.png

 

as well.

 

Counting the teeth derives the exact gear ratio, regardless of any variations in the diameter measurement. In the picture, each time the 13 teeth of the smaller gear make a revolution, 13 teeth of the larger gear will have moved, i.e. made 13/21 of a revolution or 0.62 of a revolution. As long as the gears remain meshed, the accounting of teeth and revolutions will remain perfect. So for instance gears can be used to construct a clock in which the minute hand moves exactly sixty times faster than the hour hand, regardless of the overall accuracy of the clock.

 

In a clock, when, in an hour, the minute handle moves a distance 1C, the hour handle moves a distance of 1/12 C.

 

Diameter measurements are useful for determining approximate gear ratios for non-gear linkages such as pulleys and belts. Smooth belts can slip, so even if exact pulley diameters are known quite exactly, the gear ratio may vary in operation, and may even depend on the load.

 

Belts can have teeth in them also and be coupled to gear-like pulleys. Special gears called sprockets can be coupled together with chains, as on bicycles and some motorcycles. Again, exact accounting of teeth and revolutions can be applied with these machines.

 

A belt with teeth, called the timing belt, is used in some internal combustion engines to exactly synchronize the movement of the camshaft, so that the valves open and close at the top of each cylinder at exactly the right time to the movement of each cylinder. From the time the car is driven off the lot, to the time the belt needs replacing thousands of kilometers later, it synchronizes the two shafts exactly. A chain, called a timing chain, is used on other automobiles for this purpose. In some automobiles, the camshaft and crankshaft are coupled directly together through meshed gears.

 

Thanks Bluesky. I think I've to go back primary school liao.

I think gear-ratio is used for some other calculations e.g. how fast / far gear 1 can take and so on...

[0re0]

Sound fun...

 

 

It is... especially when you know they're making a fool (or not) of themselves trying to get that number

 

(you should know right? )

[Bluesky]

The above explaination is the basic of how u would be able to derive at the ratio between the gears thus the 1:10.5, 1:11 etc..

 

Regarding how each ratio would affect the settings/speed/torque of the mobile.. I also have no idea at all

when can we take family photo?

 

manzz dun mind. once got any idea, drop me a msn msg. thanks

 

 

Now what generation liao.. no one take family portrait anymore..

 

 

When we wanna go a Neoprint shoot ah?? Try squeezing all the birds into a neoprint machine

[Bluesky]

Sound fun...

 

 

 

Is it..? I have no idea at all..

 

Nv been to one before

[Bluesky]

Manzz...

 

 

 

 

 

 

 

 

 

 

 

 

By the time u see this msg.. U should realised that my comp is off liao, my vehicle is gone liao.. and i should be on the way home to bath liao..!

 

Whhaaooooooo hOOOooooOOO!!!!!

haha okok let try.
