Did you try Google about this?

There are so many solid state devices that can cope with that problem, these days. Detecting an arc and tailoring the on/off transition is doable with fast responses and high current capability. there is much less risk of roasting contacts.

It would be a 50Ω system for RF use.

These days, if you are a standard car owner then you will plan to change it at some interval and you will need to advertise it or take it to a dealer. The vehicle's 'Service History' can be a vital part of your asking price. You will need your Owners Document stamped at the appropriate intervals...

This is all at a very low frequency so I feel that all that could be done with software (Software Defined Radio). None of that beastly soldering with many plugs and sockets and wires.

It's not clear (to me) what you actually want to achieve . I think it would be necessary to specify what the system needs to achieve before deciding on how to achieve it. A diagram always helps in these cases and avoids people chasing off in random directions. Afaics, to approach a steered...

Why not , instead of using a propane torch, use a helical heating element (glowing appropriate red) and lower the tape down through it at a suitable speed. A suitable heating element can be a helix of resistance wire, fed with say 12V and dissipating a few hundred W (similar to the power of the...

The term 'overtone' can only really describe by the layout of natural modes of vibration (of any musical or not very musical instrument) being put in ascending order of frequency. Tuning of an instrument can only be done with frequency standards (tuning forks) and a 'good ear'. It's all an...

Maybe the author used the term "symmetry" in the hope that the additional comment would help the reader. But if you are struggling to accept it or actually see what he means by it then don't lose sleep over it. The maths gives the actual answer. It's very common for students to be more...

A closed pipe forces a node at the end. The lowest frequency mode will correspond to around half the frequency of an open pipe. The bottom octave pipes are (usually?) closed so they fit into the available space. Or so I've heard. If you have a massive church, height wouldn't be restricted so the...

The first harmonic is the fundamental. The first overtone is 'over' the fundamental (zeroth tone) at (around) the second harmonic frequency. The terms can't be 'interchangeable' can they? It's like UK and US floor numbers in a multi-story building you need to know which country you're in to be...

Would the test be for your self or the bidet’s self? Strikes me as a possible candidate for YouTube. Keep us informed please. There may be a download available? (I mean an advertisement document!)

I had the equivalent of that on the rear window washer on my Skoda. It would prevent your head from being sprayed if you opened the hatchback. The Skoda electrics were a bit of a nightmare, also. The bidets I have used just had a H/C mixer tap and a jet with low trajectory. What other functions...

Other examples are available lol.

OK; bad style. If the applied three forces act at a point then they could add to zero and that could be seen as two equal resultant forces acting in opposite directions. Really - what are you arguing about here? Could you explain to me why a summative statement about the situation can't be made...
