Re: Why light weight bodies? Yes Im ready for heavy physics..

I wish I had a good slow motion camcorder. I think really, someone needs to take some tissue paper and a needle and placing it on the car and run some tests and see if it moves and to what direction, depending on where it is placed. i might try it, but no good camcorder to capture it, as thats the ...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Yet hitting this protrusion straight on would not cause the car to reverse direction like a billiard ball hitting the table rail. Actually if it was the height of the center of the wheel and enough of it was sticking out enough to make solid contact, it would... but that was not really the point I ...

Re: Why light weight bodies? Yes Im ready for heavy physics..

If the alteration is less / slower, does that lessen the amount of energy needed to correct the vector? For a car that was built to go straight down the track on a good track I would agree, however Sporty's track sounds like it is in the same condition as mine and correct me if I'm wrong but flaws ...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Let's start with the on topic stuff... I think (as dangerous as that may be) that maximizing MOI would be perfectly fine and add to the stability of a PWD car in a perfect world... however you have to consider, the tracks not perfect, the lanes are not equal, the car is not going to go down the trac...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Sporty, I like the photos... a good variety of designs and if they are all fast it helps to prove my point, I never said that cars got slower as they got thinner, some people seem to be confused because words seem to keep being put in my mouth rather than people directly quoting what I have said... ...

Re: How FAST do YOU want to GO?!?!

LOL, I know what you mean... we had a model rocket club in high school... and they are worried about kids bringing guns and such to school... I had a LARGE fishing tackle box filled with those rocket engines in my locker, I can only begin to imagine how dangerous that was looking back at things... '...

Re: Emptying the Gutters After the Race

But more seriously something like this would work great and just pump it into the sink.

Add 14 packages of KoolAid and 2 lb of sugar to the water and then hand all the kids straws. :scratching:

Re: Test Track build ? Wood prefered ?

Some one here mentioned using med or hi density fiberboard, a little heavier than the plywood but a smoother surface.

Ummm... this is kind of a mute point since the total mass doesn't change in a PWD car... we are only talking about moving the location of the mass.

Re: Why light weight bodies? Yes Im ready for heavy physics..

Sorry I didn't find anything in Sporty's post offensive... and as for my comment on Sarge's post, I think it is pretty much spot on, no malice intended... I'd like to understand what he's trying to get at but he seems to contradict most of his points by the end of his own sentence... or misunderstan...

Re: Why light weight bodies? Yes Im ready for heavy physics..

I have yet to see you prove that. I know some of us are awaiting you're testing results. Sorry. I'm not sure what your looking for me to prove... A thin light weight body that doesn't enclose the wheel has a higher drag coefficient, it is just a fact... and wether the car weighed the same as Jupite...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Actually the aerodynamics of the thinner body are [junk], the wheels stick out and mess up the air flow... light weight bodies have nothing to do with aerodynamic properties.

Re: Building a PC

Blame it on one of the patches for windows then. :wall:

You might want to check the security setting to see what was updated with the patches.
