tires and wheel

[robson]

Hello
my name is robson

I'm a participant of Formula SAE Brazil. My team's name is FastTrack.

tires question:

1. what is the temperature of work?



2.what is the air pressure?



wheel question:

1-what is the type of wheels For the tire?

SLICKS
number size
43110 19.5 x 6.5-10
43120 19.5 x 7.5-10

Since now, I apreciate your attention.

Regards,

1. what is the temperature of work?
2.what is the air pressure?
<span class="ev_code_BLUE">Racing tires get very hot due to tread flex and friction generated by rotational speed and by cornering and braking. The higher the load and the higher the speed, the hotter the tire will get. But that heat will not be distributed evenly. One tire may run hotter than the others, or one area of the contact patch may be hotter than another. If you can accurately measure tire temperatures and observe how those readings are distributed across the tire, you can adjust tire pressures and suspension to achieve improved performance. Tire air pressure is also a common question heard at the track. Unfortunately, the answer is different for every suspension, tire, track, and ambient temperature combination. (quoted from http://www.coleparmer.com/techinfo/techinfo.asp?htmlfile=Fluke-track.htm) As such, the optimum tire pressure and operating temperature is different for every car dependent on the characteristics of your car. You may like to do some tire testings so as to gather the information. A ball-part figure for the Tire pressure could be found in the tire data compilation which could be bought from the FSAE TTC @ http://www.millikenresearch.com/fsaettc.html. Trust me that it is an investment which is worth every cents you pay for.</span>

<span class="ev_code_BLUE">If you are referring to the rims, information could be found on http://www.hoosiertire.com/Fsaeinfo.htm. As for the types of wheels, I think you could try out Keizer @ http://www.keizerwheels.com/ </span>

Just before anyone starts banging on your question, I would suggest you using http://fsae.com/eve/forums?a=search&reqWords=tire+press...orum_scope=125607348 (http://fsae.com/eve/forums?a=search&reqWords=tire+pressure&use_forum_scope=on&forum_scope=125607348) and www.google.com (http://www.google.com)

It's unavoidable, the more international team start to participate, we're gonna get a lot of guys who just want a quick answer. We're also gonna have those students, who just doing it for the credit where they slack off the whole semester, and shoot a question on this board the night before the assignment is due.

I wonder if there's a better way of filtering this out.

well, one way to filter these out, is to not respond to them... right?

Well it's currently 14deg C where I'm working.

Feels about 1bar to me.

I think what we can do is to point them in the direction and give them some aid so as to assist them in learning themselves. If we had given them sufficient assistance but they do not rely on themselves, there's nothing we can do. As such, I don't think it is necessary to sound so mean to them. Chill! There is no need to lose your cool over them. I agree with you that there are bound to have students as you have mentioned but I feel that there is no harm in giving them the benefit of doubt.

My 2 cents worth of thoughts.

Damn metric units.. 14deg C.. what is that in inches? Don't you have to multiply by 3.14 or something?

[Mike Hart]

To be fair I demonstrated my Britishness there by using both Metric and Imperial units :P LOL

I think you lick your finger and stick it in the air, then guess the windspeed and divide the celcius value by the windspeed before multiplying by 4.7954696541. Pretty basic stuff tbh.

Hmm, don't you have (or had) ?N or ?Ra (for Newton and Rankine?) in the UK? So why don't you use them?! http://fsae.com/groupee_common/emoticons/icon_smile.gif

[Mike Hart]

Not in general use that I can remember, although I did come across some old test books whilst researching cooling that used deg Rankine. For as long as I can remember, the only system the general public has used is deg Celsius.
