Title: Why does wringing out a cloth cause water to leave?
Post by: hamza on 04/03/2009 18:59:43: 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??

Post by: lyner on 05/03/2009 10:02:24: 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?

Post by: lyner on 05/03/2009 15:17:04: You're torquing real sense now.
I was trying to avoid a too-techy word.

I believe it does.
