Well, all I'm really getting at here is whether I should spend more money to buy a chain that weighs about 1/2 a pound less than a cheaper chain. The bike is not moving... The idea is to just break the tires loose and slide. 3J doesn't sound like much. The engine has around 20HP.

So, is it just that easy? Since the chain is connected we can treat it all as if it were going in a straight line? We don't need this moment of inertia stuff? Because I was starting to get some weird figures using those other equations: Ig = (Mc*r1^2)/2 + (Mc*r2^2)/2 Pc = (Ig*alpha) x...

I'm confused about the angular acceleration. Wouldn't that be the same as the linear acceleration since everything is connected?

Well, if that's the worst you do on a bad day, you must be a REAL wizard once you get warmed up! Anyway, so, Ps = (.4536Kg * 3.7998 m/s/s) * (3.7998 m/s/s * 1 second) = 6.5493 Nm/s Ok, that looks like power, lol. Wait... Would the mass Mc be the mass ONLY of the part of the chain going...

Nevermind my scribblings... I think I was barking up the wrong tree anyway. :D You make it look pretty straight forward. The only thing I don't understand is alpha and wo? So, if the tire is spinning at 20 mph, then (20 miles / 60 min) * (5280 ft / 1 mile) * (12 in / 1 ft) * (1...

I'm not a student, but this seemed like the correct place to put a question. I need to know how much power it takes to accelerate a motorcycle chain weighing 1 pound in 1 second to a speed that would equal 20mph at the wheel from a dead stop. The wheel has a diameter of 20 inches. The...

Ok, here's what I've done. I used excel to find the number of times you could draw a number that sums to 11 from a lot of 2,3,4,5 digit numbers. For 2 its 8/90 or 9%. 3 its 61/900 or 7%. 4 is 279/9000 or 3%. 5 is 991/90,000 or 1%. I assume we can just add those numbers together and get...

Boy,,, I'm really burning the neuro-glucose on this one just trying to understand what you guys are talking about. And coming from a background of being handed math award after award, 8 courses of calculus and an engineering degree... I'm feeling pretty stupid about now. However, being not so...

Boy Russ, of all things to comment about in my last post your still stuck on the amount of time I spent at the hospital? :) But first,,, 10x10x10x10 = 10,000. 10,000(address)x10,000(phone)x800(date)x20?(rooms)=1,600,000,000,000. But that's not the true odds because there are many other...

Oh yes, good point... I didn't see that. Now that I think about it, there are other complicating factors like a/b addresses and odds n evens being on the north or south side of the street. What if we just assume the leading digit is eqaully distributed? If we have 9999 things, wouldn't the...

Thank you! Its ok, I understand you guys have to deal with all sorts that come here posting who knows what in an effort to change the world. Thanks again!

Thanks a lot Moonbear! I appreciate that! Let me start off by saying its funny you should mention 4 because he was on the 4th floor of the hospital that he was transferred to (thus would have a 4 in the room number) and today is the 14th, LOL. That's meant to be funny so all you serious guys...

What are the odds of anyone person having a street address where the digits sum to 11? I figure a couple of asumptions have to be made like, the number of digits in an address fit in a normally distributed curve where the mean is around 3 or 4 digits, and everyone is equally likely to have...

I'm trying.

Haven't seen the movie, but I'm going to rent it sometime. I struggled to find an 11 in many of the names of my friends and family and no matter how I arranged the names with nicknames, middle names, etc, I could not find a combo that worked. Therefore, I cannot find a pattern for anything I...
