Torque

AI Thread Summary

The discussion revolves around a homework question regarding the relationship between torque direction and gear movement. The original poster is confused about why the torque direction is indicated as opposite to that of the gears. Visual aids are provided to illustrate the question. Participants are likely to clarify the principles of torque and gear mechanics. Understanding the mechanics of torque in relation to gear rotation is crucial for solving such problems.

Here is my homework question and answer. I am not sure why the answer shows that the direction of torque is opposite of the gears.

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 'Dry sump pump issue'

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...
