The weight of your 1255 kg car is supported equally by its four tires, each inflated to a gauge pressure of 34.1 lb/in2.

What is the area of contact each tire makes with the road?

I keep getting confused on this one. Help is much appreciated. Thanks.

I know that physics is divided into the macro and micro versions, each with there own set of rules that don't apply to the other. What are the specific names of these two divisions, and why is it that we can't combine them into one huge division for physics. : /

I know that we can model a Geocentric "solar system" mathematically, with the Sun orbiting the earth and the other planets somehow spiralling round the orbiting Sun.

I imagine though that physics tells us that that cannot be the case, that the model is "innacurate" or impossible as things stand. For if the Sun (and planets) were to orbit the Earth daily, the Earth would have to have one hell of a (mass related) gravitational pull to hold such a massive and fast moving body as the Sun in orbit.

What would that (Earthly) mass be if it could hold the Sun in orbit? What calculations would I (or you) have to use to determine that? (Perhaps skip the last question, as I've seen Wikipedia's Analysis of Orbital Motion and given up right away).

How dense would it be, if it's size remained the same, and what would it be compared to, a Black Hole, collapsed dead star or Red Dwarf or something?

Everything on the Earth's surface would collapse, right, underthe G-force?

I even bet that the Geocentric model couldn't possibly be true, even if we could tamper with the masses of the Sun and planets, because with changed relative masses, the current dynamics would break down entirely. Right?

I thank anyone who can help educate me, so that I can educate others

Has anyone ever come across a program or web page that will design the wall stud size for you?

Say you have a basement wall and it is carrying 22 feet of floor load and 38 feet of roof load, the wall is 9' tall and is sheathed with 7/16" OSB with standard nailing.

I want something that will tell me what size the studs in that wall should be to meet IRC2006 code. I know there is a table in the code book but it's only applicable if the spans carried are 12' or less and that is rarely the case.

I just recently found an interest in astronomy and im looking for a telescope that will satisfy me and not leave me in regret. I want one that has great distance and a clear view. I'm currently looking at the SkyQuest XT10 Classic. If there are other telescopes in witch you think are better I would be glad to know. Thanks.
