It would be for a tip-over mast for some WX instrumentation in a very rural area away from people and buildings so there is not much risk for injury. In addition the bending moment would be at its worst only when moving it to the horizontal position. The cross sectional area of the...

If you were to mate a 1 ½” black iron pipe to a 1 ¼” black iron pipe using a 1 ½” coupling and a bushing reducer, how much bending torque would be needed before one of the parts or connections failed? That is, if you held the 1 ½” black iron pipe in a fixed position and the applied a force to...

I used the term complex and composite wave to indeed mean a single wave that is the result of the superposition of two or more waves that cannot be “easily” expressed in mathematical terms. Thanks again for taking the time to answer. It helped clear up a few questions for me.

First of all I would like to thank you both for taking the time to reply. In response to PAM. I can understand why it has to be coherent to produce the nice banding in Young’s experiment, but I am afraid the rest still eludes me. Just saying you need coherent signals, doesn’t answer...

There are hundreds, if not thousands, of RF signals all around us from those at VLF frequencies to microwave frequencies and I suspect if you set up a very long random length of wire as an antenna, there would be a resulting induced electrical signal that is the sum (and differences) of all...
