what is the phenomena involved when we twist a wet cloth. what causes the water to fall out of the cloth when we twist the cloth. Is it Inertia??

If I had to guess, I'd say that it is due to compression. When you twist the cloth, presumably the fibers get closer to one-another and there is less room for the water.

That sounds eminently reasonable and is, in fact, what I was going to say.

I'd go with that, too. You can get much more pressure between the fibres when you 'wring out' the cloth than when you just squeeze. There must be, effectively, some leverage due to the turning action.

Would that be torque?

You're torquing real sense now.
I was trying to avoid a too-techy word.

So does that rule out inertia??

I believe it does.
