    Water Pressure in Box: Calculating Perspex Thickness

    Thanks, Ill see if the local Univ library has it. Nice, now that’s what I am talking about. I had a chat to my brother in law, who does mechanical modeling, however he has little experience in designing something to accommodate bending, as Aleph mentioned. He does have modeling software...

    Water Pressure in Box: Calculating Perspex Thickness

    Dear All I have approximately 300liters of water that I would like to house in a box. However I would like to check up on my water every now and again so I would like to make it out of clear perspex/acrylic. I could make it out of glass, but perspex is cheaper and easier for me to handle...

    Understanding Current Inrush on Device Activation

    Sophie, thanks for the reply. The electromagnetic field propagation I can understand, but on the scales I am working on, the field is in the 300HMz and above range (or 3.3ns and shorter). My concern lies in the milliseconds to hundreds of milliseconds. I will continue my search in the...

    I cast: "Revive thread": I am working on a device that could be considered an electric generator, but it can be simply viewed as a transformer. In investigating the magnetic field I have been informed that "an inductor is not an inductor all the time". Apart from knowing that a real world...
