Slot Cars
Hi Guys
I was just watching a program where there was some slot car racing. They said the cars were 1:32 scale. And then they raced down the track and measured the speed. When the speed was recorded they multiplied it by 32 and came out with values around 6-900 MPH.
This seems incorrect to me, what do you think?

Re: Slot Cars
900 mph is a little fast!
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Hi Dave
I think that's wrong. Just because the model is built to a scale why should it be ok to scale the speed similarly.
The recorded speed is the speed. No scaling necessary or appropriate.
Otherwise when I put my daughter's Sindy doll in my son's Millenium Falcon and throw them together across the room, they are travelling at different speeds ????
And if I have a Porsche made that is twice the normal size, I don't think the police will accept that argument when I'm caught speeding.
You were right to be suspicious.

ps. Apologies for the non-politically-correct choice of toys. But don't blame me; it's what they wanted.

Re: Slot Cars
Hi Bobby and Bob
Yes I thought it was very wrong. Just wanted to discuss the matter and clarify it with the dudes.
Also it crashed and flew about 2m into the air. So by their reckoning that's 192m or 629.921ft
Fantastic!
Hows things anyway? Hope all is well with you both.

Re: Slot Cars
Hi Dave,
Good to hear from you. I'm fine. In the throws of decorating the lounge ... and relatives, 2 + 3 kids, want to come and stay.
Where to put everything? Now if I could scale things a bit (selectively of course)
Hhhhmmmm.

Re: Slot Cars
Cool, good to hear you are o.k
Yes some scaling sounds like it would be just the job.
Things are still the same here, got an interview on the 4th. Not that bothered about it to be honest. IT Dogsbody, Bahhh!! Rubbish! . So i've started to work on building a Chroma Key program in MATLAB. Far more interesting.
