August 18, 200521 yr well after join in TV member for a while ....before u start to be a member ..u need to apply and choose the name ... so what i want to know is...your ID imply something? have any meaning me BambinA = a little girl ... well i choose it coz im always a baby silly girl i try to guess (just copy who online right now) thaibebop - he is in TH and be "bop" Thomas_Merton - it'd be his real name bangbuathongben- should be Ben who live in Bangbauthong cobra - hmmmm sound dangerous Lord Toad - frog's friend? The_Moog - emmmm , but in thai Moog(k) = pearl khall64au- must be a girl name K who come from Aus mrbojangles - Mr Boj who love mathmetic stuff bossman- bossy man> Khun Jean- Mr .Jean Ice Maiden - hmmmm tell me then Totster - how about you danny? britmaveric - come from UK? tukyleith - hard to guess Pattayaman- a man who lives in PTY JustAnotherFarang - make sense Rinrada- this is my real name think_too_mut - too much for think? sabai dee - im fine too Nepal4me- from Nepal? Boo- peek a BOO loong - uncle Firefoxx- sound like a web browser CarlBkk - carl who live in Bkk Boon Mee - that is Thai name Bambi ps...by the way there are more ID name who online now, i just dont know how to guess
August 18, 200521 yr My TV nick is a version of my nickname which I have had since I was about 9yrs or 10yrs old... mrbojangles - Mr Boj who love mathmetic stuff totster
August 18, 200521 yr Author My TV nick is a version of my nickname which I have had since I was about 9yrs or 10yrs old... mrbojangles - Mr Boj who love mathmetic stuff totster <{POST_SNAPBACK}> jing? danny...sound too diff from your name BTW hope Mr. Boj who love math love 69 number
August 18, 200521 yr Author I'm called dave and i live in thailand <{POST_SNAPBACK}> more than make sense David who live in PTY Thailand
August 18, 200521 yr My TV nick is a version of my nickname which I have had since I was about 9yrs or 10yrs old... mrbojangles - Mr Boj who love mathmetic stuff totster <{POST_SNAPBACK}> jing? danny...sound too diff from your name BTW hope Mr. Boj who love math love 69 number <{POST_SNAPBACK}> Lol. My nickname basically says it all. I'm cold and biatchy also explains my fair skin. And "maiden" means an unmarried girl or woman . But I'm not always an Ice Maiden
August 18, 200521 yr Yup Loong, because nearly everyone in the village calls me uncle. Even if they are older than me
August 18, 200521 yr Author Nick name since youngster was maveric. I'm british. EasyPeasy!!! <{POST_SNAPBACK}> i confest that i always imagine u are ..Mel Gibson from 1994 "Maverick" My nickname basically says it all. I'm cold and biatchy also explains my fair skin. And "maiden" means an unmarried girl or woman . But I'm not always an Ice Maiden <{POST_SNAPBACK}> talok mak mak Gold star Bambi! I'm "a girl name K who come from Aus" <{POST_SNAPBACK}> i knew what K stand for ..but i wont tell anyone lol LAMOK totster <{POST_SNAPBACK}> mai lomok mak .. just a lil
August 18, 200521 yr Author just see this TV memb in this thread "ProfessorFart" he must get doctoral degree for blow up!! (please dont do that in life or elevator please .. i beg u Bambi
August 18, 200521 yr My TV nick is a version of my nickname which I have had since I was about 9yrs or 10yrs old... mrbojangles - Mr Boj who love mathmetic stuff totster jing? danny...sound too diff from your name BTW hope Mr. Boj who love math love 69 number Hey Bambi, yeah 69 is about the only number i love. I would be intrigued to know how you came about the theory that i love mathematic stuff. This should make great reading

August 18, 200521 yr Author Add more (tell me if i guess wrong) khunlungphudhu - its TH name ..ancient hi-so guy and pooh dee sadako- sound like a ghost from "the ring" movie FreedomDude- emmmm make sense traveller57 - a back packer who born in1957? bkkbrad - i know him , a brit who worked in BKK S1MON - Simon sexonlegs- cheeky Sangsom - TH whiskey wooooooooh ... bambi Edited August 18, 200521 yr by BambinA
August 18, 200521 yr mrbojangles - Mr Boj who love mathmetic stuff And for todays lesson boys and girls, we are going to build a rocket. Homework to be handed in to me tomorrow evening. Let's use an Estes Alpha III, to keep it basic: Weight: 1.2 ounces empty. I will add 0.7 ounces for the engine. Diameter: 0.976 inches Motor: C6-7 (we'll use a big one for this rocket) Now let's follow the equations above and see what we get: Compute the Useful Terms Mass of the rocket M = (weight in ounces)/16/2.2 = (1.2+0.7) / 16 / 2.2 = 0.05398 kg Area of the rocket: A = pi*r^2 = 3.14*(0.5*0.976/12*0.3048)^2 = 0.000483 m^2 Compute wind resistance factor: k = 0.5*rho*Cd*A = 0.5*1.2*0.75*0.000483 = 0.000217 A C6 motor has a nominal impulse of 10 N-s and thrust of 6 N. The "rating" cited above applies to the impulse, giving us an actual impulse for an Estes C6 of 10*90% = 9 N-s. Compute the burn time t = I / T = 9 / 6 = 1.5 sec. The gravitational force = M*9.8 = 0.05398*9.8 = 0.529 newton Compute My Terms q = sqrt([T - M*g] / k) = sqrt([6 - 0.05398*9.8] / 0.000217) = 158.8 x = 2*k*q / M = 2*0.000217*158.8 / 0.05398 = 1.277 Now the good stuff: v = q*[1-exp(-x*t)] / [1+exp(-x*t)] = 158.8*[1-exp(-1.277*1.5)] / [1+exp(-1.277*1.5)] = 118.0 m/s if this number doesn't mean anything to you, multiply by 2.237 to get velocity at burn-out in mph: 118.0*2.237 = 264.0 mph! And you won't get a ticket! yb = [-M / (2*k)]*ln([T - M*g - k*v^2] / [T - M*g]) = [-0.05398 / (2*0.000217)]*ln([6 - 0.05398*9.8 - 0.000217*118.0^2] / [6 - 0.05398*9.8]) = 99.95 m remember this is the height reached during boost. Multiply by 3.3 to get it in feet: 99.95*3.3 = 329.8 feet. yc = [+M / (2*k)]*ln([M*g + k*v^2] / [M*g]) = [+0.05398 / (2*0.000217)]*ln([0.05398*9.8 + 0.000217*118.0^2] / [0.05398*9.8]) = 236.8 m = 781.4 feet. Notice: the rocket goes more than twice as far after the burn as during the burn! AND THE TOTAL ALTITUDE IS... yb + yc = 329.8 + 781.4 = 1,111 feet

August 18, 200521 yr i reckon the final answer = 69 Correcto Mundo but don't tell anybody else Bambi, they have still got to hand their homework in Edited August 18, 200521 yr by mrbojangles
August 18, 200521 yr i reckon the final answer = 69 <{POST_SNAPBACK}> Correcto Mundo but don't tell anybody else Bambi, they have still got to hand their homework in <{POST_SNAPBACK}> . I was never one for handing homework in
August 18, 200521 yr Author . I was never one for handing homework in <{POST_SNAPBACK}> this is your homework 23x3 =?
August 18, 200521 yr . I was never one for handing homework in <{POST_SNAPBACK}> this is your homework 23x3 =? <{POST_SNAPBACK}> The answer is 69
August 18, 200521 yr . I was never one for handing homework in <{POST_SNAPBACK}> this is your homework 23x3 =? <{POST_SNAPBACK}> 41 ? sorry, private joke.
August 18, 200521 yr Khun Jean because it is my name and i like it. So much easier than hiding behind a nickname. I had another one before although not here. It was "Brainless". I changed it because it was to revealing.

August 18, 200521 yr My friends have called me zaz for a very long time so this is the name practically everyone knows me by.

OOps sorry. Libertarian. not librarian! Anyway 23 x 3 = well I could tell you the answer in Russian, but its rather a mouthfull 23 x 3 = sometimes only 34 and half (think about it) 23 x 3 = sometimes "I no like*
August 18, 200521 yr 23 x 3 = well I could tell you the answer in Russian, but its rather a mouthfull <{POST_SNAPBACK}> So is 69... totster
August 18, 200521 yr Author seem 69 is magic number u guys should buy 69 lotto if somebody get a jackpot...share me then
