IF you mutiply dy/((e^-y)+1) by (e^y)/(e^y) before intetgrating, can you then use integration by substitution?

CW and CCW stand for Clock Wise and Counter Clock Wise. I just got done doing this stuff a few weeks ago, so i know what you are going through. What they are trying to tell you is that the normal force of each wheel (and the associated torque) counters the load on the wheel from the car. You...

You're quite right. I talked this over with some class mates who have a better understanding than i do, and they agreed, saying that it has to be a pressure change, not a velocity change. It seems counter intuitive to me, but it does help me get my assginment done. So I'll take that as my...

OK, good night then. And roger on the EoC: IF mass flow rate can't vary in a tube (flow is laminar and fluid is incompressible), and cross sectional area remains constant, then the only thing that can vary with height is pressure. Looks like I'm still stuck...

Good point. But not necesary, i think i have it now. Like you said, the stream narrows when its not in a pipe. And what I kept forgeting is: the pressure can't really be all that different in a pipe where the water is falling. I figured this by considering a pipe closed at one end, and then...

I would think carefully about what andrevdh said, and dust off the old trig. textbook. Think of the problem as a SSS triangle, and then think Law of Cosines. Good Luck!

So, I'm tweaking my understanding of applying Bernoulli's equation, and I'm having a problem understanding the change in pressure and velocity when a fluid flows down a tube of constant diameter. The way i see it; either the pressure changes with height and the velocity stays the same, or the...

Rolling, Rolling, Rolling... Thanks so much for your help. I've spent the last 36hours working, eating, sleeping, and trying to understand what you said. I think I have it now, and here it is for anyone else who reads this. So, the axis of rotation(of the wheel) is also rotaing in...

OK, I usually like to work this stuff out on my own, or limp along. So, if i didn't think i was a little over my head, i wouldn'y be starting this thread. I am aproaching a test that will include all the stuff on angular: velocity, acceleration, momentum, torque, and moments of inertia...

Well, I had a cool post, but then the cat walked on the keyboard *grin* I think it went something like this: I think we all agree that the problem with discussing sensing the future is two fold; One: We don't have a clear answer as to the relationship of perception and consciousness. We...

Agreed, but our "subconscious" is an extremely organized neural network with millions of discrete componets and nodes. So its not as simple as just chemistry. There is definately some complex behavior going on, involving lots of different inputs. I think our subconscious does inform our...

It seems a little premature to be probing into the posibility of civilazation on Mars when scientists here on Earth have their hands full with questions about strange and hard to place artifacts, and all we have from Mars are arial surveys and a few photos from the martian surface. (by...

fascinating topic,,, is it in the correct forum? oh well... I have often wondered about some of this stuff myself. Is there anyway to design an experiment that could detect the latency in the way the brain gets its information? Although I could be wrong, I feel confident that such latency...

Thank you very much, Marcus. The more I read the other threads, the more simple and naive the idea seemed. But I ran out of my own steam and needed help. It just seems odd, weird even, that with every passing moment there is more & more nothing between everything. Could It be the universe...

Hi, just read the post about 4D spaces, and I think I might actually be able to add something. When trying to imagine a true 4D+ space, I like to think of the kind of scenario you might see on the twilight zone, where some people find themselves stuck in a furnished house that has a snow globe...
