I am looking at using wire spec M27500-20LE1S05 in place of M27500-20LE1G05. The major difference is the wire braided for the shielding would be round silver coated copper instead of flat. I am trying to determine how much of a factor the shape of the shielding wire is. As a mere mechanical...

I am trying to reverse engineer a retaining ring for a piston. The retaining ring was under hardened. The piston has a flange that strikes the retaining ring. Both the flange and the retaining ring are relatively short and thick, so plate analysis for absorbed energy is not a feasible...

I have erossion pitting in an inch and a half diameter tube. I need an easy method for measuring extend of pitting, to put a measurement value on failure/nonfailure of the part. What kinds of easy, cheap measurement methods are available?

I am seeking a corrossion inhibitor for a use on 4130 and 4140 steels. Cadmium is the present product in use, but is no longer feasible due to bioenvironmental concerns. I need a coating that is either durable enough not to come off or scratch in rough handling environments, with sub-zero to...

I have a solenoid circuit with two zener diodes faced opposite in parallel with the coil. I don't understand the function in a DC circuit of this arrangement. Any insight would be helpful. I know in an AC circuit, two zeners facing each other, rather than opposite each other, will clip the AC...
