Song playing is called " wish " by s.e.n.s. I choose this song because, it can help you to relax and help you think better. And to generate more ideas. XP and i personally love this song a lot. XD

uh oh! haha. later mr soo deduct my marks... =[
so long never post... cause school reopen already...
then im so busy... :D haha. kkiee... hmms...
last time talk about gears...
this time talk abt ratchets:D
hmmms... whats that nerh? :D
The ratchet is really another form of gearing.
Unlike gears which can be used to speed up or slow down movement,
the ratchet can only be used to slow things down and it happens in a very jerky manner.:D
below is a simple example. ^^



and for this example, when the crank turns 8 rounds, the ratchet will turn 8 rounds.
because there are 8 " teeths "

Below is a 3D drawing of a simple ratchet.
There are not many moving parts to make but as with all mechanical things you do have to work out fairly accurately the size and distance of all the various components.



okiie... you know roughly what does ratchet looks like...
so... i got to go lerh:D

yoyo! so long then post again... alot things happened...
anyway... today talk abt gears... the mechanisms... XD
GEARS
the way gears works(:
Gears are very versatile and can help produce a range of movements that can be used to control the speed of action.
In basic terms, gears are comparable to continuously applied levers, as one tooth is engaging, another is disengaging.

The gear wheel being turned is called the input gear and the one it drives is called the output gear.
means example u turn gear A, that means it is a input gear.
and the other gear B is output gear... should be right? haha...

Gears with unequal numbers of teeth alter the speed between the input and out put.
it means... one is fast one is slow... right? haha X)
This is referred to as the Gear Ratio.
the ratio is counted like that ...
number of teeth on the output gear B (30)
number of teeth on the input gear A (10)

and simply, the ratio is 3:1 !
the output must be over the input.
means, when gear A turns 1 rounds, gear B turn 1/3 round only... XDD
yea! i discover something... and realise how stupid am i... haha. X)
and horhs...! i see the picture of the mechanical toy that uses gears as mechanisms horhs... its so complicated! i don't know how it works lehs! T.T
i show u those pictures... (:


espeacially this one below... its so complicated! T.T

i wonder how do they think of this kind of things... haha...
kk... i still got alot of things to do... somemore my journal still haven do finish... hehe... X)) kk... byebye! (:
