electric machinery fundamentals by chapman looks pretty nice, good overview of the theory. "from scratch" sounds like a pretty massive task you're better off finding the design detail of the motor you'd like to make and just getting gud at making stuff, you don't really get that from a book.

The speed of sound is actually inversely proportional to the square root of density (meaning that all else constant, higher density means slower speed of sound). The property you care about is bulk modulus, which is a measure of how hard it is to compress a substance. The gap between speed of sound in steel v. speed of light is like 5 orders of magnitude btw, so the answer is safely "no". There's a derivation a couple threads back if ur interested

1) listen to the song itself
2) listen to a different, catchier song

Yes it should still technically work, but it would be hampered. A good reason to pick design 1 over 2 is you allow for more gas expansion and thus more work to be done on the pressured surfaces of blue and yellow, which means ultimately more energy granted to the countermass (also, less energy in any gas that is ported from the rifle). This means the countermass accelerates forward faster and you get even more of that balancing effect. Nice drawings btw.

curves? like direction fields? paul's online notes
