1. @Ritesh, Can you please give the full sentence exactly given by PK Nag in the book.
Also give in what concern this equation comes in the book?

1. @Dinesh, Right now I have P N Rao’s “Manufacturing Technology” book for this section!!!
Also I have some notes from various books; one of my professor given those notes to me ðŸ™‚

1. Thanks Dinesh for giving out book names, I am trying to get these books & I will reply on it soon…
The “Scribd” web-link is also good.
Did you know How to download the documents from Scribd by the way?

1. Thanks!!!! I know I am not so good to Explain something but still I tried my best.

1. If you see previous years GATE question papers then you will find that most of the questions came from Operation Research part. On Pro-Planning, the question comes after 2-3 years. So at last if you have the time then only prepare for this section.

1. This is my second attempt.
Anyway I am not actually bothering too much about “Mechanics” bz I know if I prepare for SOM, TOM, Vibration & DOME well then the “Mechanics-Problems” will be automatically prepared!
Remaining theory part concepts can be prepared from any standard book.
Also you will see there are hardly 1 or 2 questions on the Mechanics Section!!!!

1. Ritesh, Please inform me if u got some information about any book or any website where we can get some quality information for this section…

1. @Ritesh: Absolutely it is always be zero. Work = Integration of P*dV. Now as Volume is constant it means change in volume is zero i.e. dV is zero, which results in zero work done.
Lets took it in this way. Consider the standard “Piston-Cylinder” example. Whatever u do in the system (either change pressure or Temp.) but its volume is going to be same as it is Constant Volume process. So if u remember the definition of “Work” ; it is Force*Displacement. So it requires “Displacement”
In this process there is no displacement of the piston because it will change the Volume of the cylinder so it will violet our essential requirement of “Constant Volume”. And also as it is “Closed System” no mass can cross the boundary of system so that there is no chance of Work to be done on the mass so it could cross the boundary.
So moral of the story is “For a Closed System Constant Volume process work done will ALWAYS be zero”

1. If you are feeling it tough then I think you should start with simple topics like PERT, CPM, Transportation, assignment, network analysis etc. solve as many problems on this & ones you feel confidence on these topics then you can go for difficult ones.

1. @Ritesh: yes you are right! I actually forgot to delete it from the list… Thanks a lot, next time I will be more careful.
