Spring: about 5 in dia x 9 in tall barrel style coil spring using about .5 in wire. Fully compresed height is roughly 1.5 in.
Fatigue test: cycle spring from almost compressed height to about 4 in height at some rate until it breaks.
Question: How does that rate affect the life of the spring?
I've been poking around the web for a cylinder that can perform dampening and actuating. A standard shock absorber (like your car's) simply passes fluid from one side of the piston to the other through an orifice or valve or something to slow it down. Closing that would make the thing a normal...
My SSR is rated:
Input 105-130 VAC 3VA, Contacts 125VAC 1/3Hp
I know that very little current is required to operate it, and they do trickle some current through closed contacts.
What are the chances that (OK, I mean parameters that will cause) a closed contact will leak enough current to...
