Luf Sir's comment is apt.

How can one with 'lots of confusion' tell his 'practice to give rotational moment in front of any nozzles' as correct?

'When i tried to reduce the moment at the nozzle load i used RX, RY, RZ it reduces the load & now i want to know, is it possible to restrict only the moments without forces & i also need where i get more information about ROTATIONAL RESTRAINT.' - Arun Kumar's this entry shows he needs some formal training!
