AI Thread Summary
The discussion focuses on the search for very accurate motors, specifically piezoelectric and ceramic motors capable of nanometer precision in both linear and rotary movements. Participants express curiosity about the existence of rotary nanomotors that can be practically applied, questioning their torque capabilities. Mention of "nanomotors" highlights their limited application on silicon wafers, raising concerns about their utility. The conversation also references magnetostriction and specific quartz crystal cuts that can twist under voltage, indicating potential avenues for rotary motion. Overall, the thread explores the advancements and limitations of piezoelectric and ceramic motors in nanotechnology.

I am searching in google after professors websites or articles \ papers or video lectures in very accurate motors (1 nanometer), that use the principles of piezoelectric and ceramic motor movement, that can move in linear and rotate movement and they are rapid, and very small, if you know about good websites in this area so I will glad to know about that

That thing is astounding! I wonder, though, if anything of a rotary nature (as iii mentioned as part of the question) exists? I've seen "nanomotors" that just rotate on or in a silicon wafer, but can they actually be connected to anything in order to be useful? My concern is that there can't be a lot of torque there.
 
"Rotary?" See "magnetostriction." There are "cuts" of quartz crystals, and other piezoelectric materials, that will actually "twist" under applied voltages. Don't ask me for details --- that was a "dead end" technical work-around on which very little time was spent a very long time ago.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
