    Relate Two Vectors to an Angle?

    Glad it worked VX967! I just realized you may be able to just use n_{xk}=x_k and n_{yk}=y_k. I believe that would be equivalent to the just using the 'z-term' of the cross-product. If you find yourself needing a bit more speed out of the code, you may try that. That is the problem though, I...

    Sealing a low-vacuum closed system

    Thanks for the suggestions! I like the idea of coating the inside of the copper tube with solder, heating and crimping it. Sounds like it will work great. I think I may need to be clear about the glass, I will make the chambers out of copper/aluminum. The chamber will not be much more than a...

    Sealing a low-vacuum closed system

    Thanks again Q_Goest, that is what I needed to hear. My experience with vacuum systems was a week long session required for my Engineering Physics degree. We operated a lot of vacuum equipment, all I remember was how easily leaks could botch pumping @ 10^-6 torr. I have read a number of articles...

    Sealing a low-vacuum closed system

    Already drafted a response and lost it because the system logged me off... urgh. Thanks for the response, Q_Goest, I was beginning to get the impression that sealing wouldn't be difficult but I have a couple questions still. I can get compression fittings and valves rated for 29.9" Hg vacuum...

    Relate Two Vectors to an Angle?

    I'm going to assume that z=0 for both vectors, otherwise you do not have enough information to determine the angle correctly within the kart's frame of reference (i.e. this solution assumes that 'up' for the kart is always (0,0,1)). Assuming that, you are only dealing with (x,y) vectors and the...

    Sealing a low-vacuum closed system

    I've been researching this for quite a while and feel somewhat exasperated, so I thought I would ask more knowledgeable folk. I need to seal a closed system for low vacuum, and I need to do it on a budget. My problem is that most of the information I have found deals with much higher vacuums...
