AI Thread Summary
The abnormal motions of a volleyball after it passes the net can be attributed to its non-spherical shape and the effects of spin. When the ball is struck with little or no spin, its surface features can cause it to move erratically, similar to a knuckleball in baseball. This phenomenon is particularly pronounced in outdoor beach volleyball, where wind conditions further complicate the ball's trajectory. The interaction of the ball with air creates unpredictable lateral movements, making it challenging for players to receive and control. Understanding these dynamics can enhance gameplay strategies and improve handling techniques.

Why while playing volleyball after the ball passes the net it shows some abnormal motions?

It's similar to a "knuckle ball" in baseball. The volleyball has some features on it -- it's not perfectly round. So if it has little or no spin, the features will cause the ball to move a bit side-to-side. That's why on serves and spikes, you try to hit the ball so it has no spin.

You especially see this effect in outdoor beach volleyball, when serving or spiking into the wind. It makes it very difficult to handle the ball with your bump :biggrin:
 
Thanks,but if you could say it in more scientific language it'll be very good,I'm an aerospace enginner and curious about this!

It's starting to sound like homework. Why don't you try phrasing it in aerodynamic language for us? You could look up knuckleball on wikipedia.org to get you started...
 

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...
