Hello, I am working on a project and I came across a question that is a little beyond my skill set. I am designing a support for a roof, and I have the force into the post, the length of the post and I need to determine what pipe I need, size, schedule diamter, etc. How do I go about this...

I realize this question is a bit outdated but incase anyone else looks at it... btw I rather liked the location joke, From what I have found a 3.3 is a decent score for grad apps, though common, the school of origin doesn't have as much effect as scores, There are many ChemE grad...

Sorry I didn't get back to you sooner, . Specific projects exhist in all the areas that were mentioned.Each with an extensive project discription. I was only general in an attempt to find out what field might be funded easier. This is the main development lab for the school, it has just been...

Wasn't really sure where to put this post, Here is the short version I am a student who is trying to restart a research lab on campus that is highly publicized but inactive, much to my dismay as a transfer student. I have discussed it with faculty and admin, however without outside funding...

ditch the car dealership, you could make it work for psych if you twisted it but you would be better off volunteering at an ESL program(cultural sensitivity pads the app nicely) Since your not sure where your interests are, focus on becoming involved with leadership. It goes into all degrees...

thermal energy per power was my first thought

Is there a relation that connects a current with the diameter of a material for efficient transfer of thermal energy. I say diameter as I think its safe to assume heat leaves radially given a uniform material. I am also looking for a relation between resistance of a material and heat...

Interesting, I believe you will, as you have probably guessed dealing with a basic parabolic trajectory, My suggestion would be to install some sort of blocker near the end of the roof, to slow the water so it falls straight, or close to, if not it will shoot off quite far, you can look up basic...

Thanks for the reply's, I've been off for a while, you know how it is, out of class and work,try to focus on something else for a bit :wink: I hadn't thought about the thermal balance, interesting concept though, So theory question, If one was trying to maximize the heat generated by a system...

Interesting, so that brings up another question. If to calculate it in an aqueous solution involves working around resistance. If one was trying to minimize heat, use a material that behaves in a manner decreasing resistance with current, and to maximize use one that does the opposite?, That...

Ive posted this a while back but never had a reply, How does one determine the heat generated from a current? I have found several sources that refer to using "the length of a wire" but how would you calculate it for an aqueous material, or for all intensive purposes a "really large" battery...

With out going through it step by step, it looks right and your answer is close enough to reason that, try carrying the values to an extra digit to remove possible rounding errors.

Homework Statement an electron is accelerated through a potential difference from 0v to N kv. It is then ejected through a slit and deflected 10* over a distance r of 2 cm. find B ,v_f, and t(time) Homework Equations qdelta V = 1/2Me v_f^2 (solved for vf) M(v/r)=...

Would this qualify as high sym.? The way I was going to approach it was calculate the force on the particle due to the two verticle lengths of wires, since it would just be the force due to 1*2, then add the effect of the upper horizontal wire to that. But how do you calculate the first...

I know the results for infinite, but how about finite? And where is the cutoff with the aproximation of infinite? I've heard the value 10% tossed around is that right?
