Thank You Sir.

So (pv) itself is a property of the system? From where I read, may be older text, (pv) is referred to as flow energy or displacement energy, the energy due to the bulk of a moving fluid or the energy content of a static fluid due to the volume it occupies. Is that a correct thing?

Sorry Sir, I mistakenly wrote dV instead dv. So in this d(pv) any work can be included? Starting from expansion compression work in closed system to flow work in Open system? What kind of Works does this d(pv) include? What is exact significance of (pv)? Can you explain in brief?

I just wanted to ask that, if dh = du + pdV is valid, then we can change volume through different processes and change dh by different amount between two same states. What is wrong in this thinking? [I removed the previous question, because I thought my Statement was not completely understood]

Thank you. This must be the explanation. But this confusion is never encountered in general Engineering Mechanics course. Nowhere it is said, that the two lengths are different. Very interesting fact is discovered here. The factors |DA||BC| & |DA×BC|... Their physical difference is...

Yes, me too discovered the same ratio. And according to magnitude laws... Moment Arm is always shorter than Common Perpendicular. But they should have been the Same! Very Intriguing. I Think so... There is no other way to Explain it. But it is quite hard to visualize in mind. Because common...

Not only the Problem I have attached in Picture, but there are few more where I get different answer while solving by taking Moment Component and by Common Perpendicular. [NB : The problem Stated in 'Engineering Mechanics' by Ferdinand L. Singer. Process 3 is what I did, Process 1 is what is...

In which country you are studying?

They seem to be Very correct if there is no F.

Yes, that is True,it never holds unless it is a Static Equilibrium. That is why I always Prefer to Draw the accelerations when Inertial Frame is not Used, it avoids confusion. By the way Thank you Sir, for Guidance.

These Equations are Correct. And my Apologies, if I made anything Complicated.

I had drawn all the Diagrams... I don't think i considered anybody is in Static Equilibrium. They are all in Dynamic Equilibrium and All Inertia Forces should be Shown. And even if Dynamic Equilibrium is not drawn, at least accelerations with Direction is shown, which was not In diagram making...

But that is What Free Body Diagram of Object 2 Shows on using Equilibrium along Horizontal axis.

I am really Sorry for the Emoticons... I was in Hurry and somehow my Browser added them. But they are not a Problem to Understand the Theory, Fortunately!
