nvn: Thanks for the reply. The way I drew the diagram is a bit misleading in that respect. I just wanted to represent the different sections. It is not literally built the way I drew it. There are actually about 16 separate sections that make up this form, and they are connected to the air...

Quick diagram Here is a quick diagram to help you visualize what I have described.

If this is in the wrong section, please let me know. I will gladly re-post to the correct area. Here is a real problem we face at work, and I would like some help quantifying it. We have a round form, whose diameter is adjustable. Air cylinders are used to expand or contract the overall...

Does anyone else have an idea of how these magnetic bases work?

No, they are not electromagnets. They are simply a free standing base, which is what makes them (in my eyes) so amazing. They do not plug in, connect, or use batteries. You can simply put them on a para (ferro) magnetic material, switch to "on", and they stick like crazy. Has anyone else...

At work we have these magnetic blocks which have arms attached to them for dial indicators. They are use to hold the dial indicators like an extra pair of hands. They work great. My question is how do they work!? The magnetic block has a switch on it. This switch will turn the magnet on...

Check out this link: http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html The section that is labeled "Electron Transistions." This info (formula) ought to be in your textbook too.

No takers on this question? I know I have shown no work, but I am completely stuck. Can anyone gander atleast a starting point?

I do not even really know where to begin with this problem. Any help would be great. Q. Write an expression for a P-State (linearly polarized) lightwave of angular frequency \omega and amplitude E_{0} propogating along a line in the xy-plane at 45 degress to the x-axis and having its...

Thanks a lot for the tip. In that case I think I need to remove the exponent of n on the cos function. Is that right? If so, that probably makes it much easier to deal with. I will try to work through that scenario later and post my result. If that is the wrong approach, please let me...

dextercioby, thanks for the reply. As for the question, it definitely states an infinite box. Do you think this could be an error in the question? I know what you mean by the formula you provided. We did go over that in class. I also follow you on the fact that this is one dimension. I...

I have a question regarding the expectation value of particle: "Obtain an expression for the expectation value <p_{x}^n> where n is 1,2,3... of a particle in an infinite box (U = infinity for x<0 and x>L; U=0 for 0<x<L) which is in an eigenstate of the energy." That is the question word...

Is anyone familiar with the Basic STAMP 2 microcontoller? I have found a little information about it, but not much. I would like to start tinkering around with some type of microcontroller, probably something to run stepper motors. Would this be a good choice? Specifically, I am thinking...

OK, here is what I have now: Let r=red and v=violet \frac{sin\theta_v}{sin\theta_r} = \frac{\lambda_v}{\lambda_r} Let: \theta_r = \theta_v + 20 Sub in for \theta_r to get: \frac{sin\theta_v}{sin\theta_v + 20} = \frac{\lambda_v}{\lambda_r} Now trying to solve for...

Maybe it's late and I am not thinking too well, but I am stuck on applying the trig identities. I figure to use the sum formula for sin(A+B). I get to sin(\theta_2 + 20) = \lambda_1 sin(\theta_2)cos(20) + cos(\theta_2)sin(20) = 430nm Now how to solve for \theta_2 ...
