Witness the Shuttle's Final Launch: A Time-Lapse Movie

AI Thread Summary
The discussion highlights the impressive engineering of the space shuttle, emphasizing its significance despite debates over its effectiveness for orbital transport. A time-lapse movie showcasing the shuttle's final launch day is shared, providing a visual treat for viewers. Observations include the nervousness of the crane operator and the interesting movement of the shuttle during rotation. The time-lapse speed allows for calculations related to the shuttle's behavior as a torsional pendulum. Overall, the thread celebrates the shuttle's legacy and engineering marvel.

Whatever you think of the shuttle as an effective way of getting stuff to orbit it's still a cool piece of engineering. Here is a time-lapse movie of it's last day at work.

ps. sorry you have to watch a 20sec ad first

pps. that's got to be one nervous crane operator!

Wow. Very cool. I like the little wiggle you get when the shuttle is rotated. If you knew how fast the time lapse is, you could calculate the period of the shuttle as a torsional pendulum!
 
The link explains how they did it, although i assume they didn't do a constant rate throughout.
 
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...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
