There was talk here physics.stackexchange.com/questions/401/… about programs to make physics diagrams. What I'd like to know is which software made diagram such as these:
and
From Engineering mechanics by Hibbeler. I do not think it is inkscape. I do not think it is Visio either. I wish I know. book does not say. Send email once to publisher, never got reply

Why did this question put this question off topic. It is not off topic. — user35509 37 mins ago
I'm a little curious about why you, as a newcomer, think you're entitled to tell the rest of us what is or isn't off topic on our site. ;-) Of course, you're allowed to ask for clarification as to why your question was closed; sometimes we do make the wrong decision, and we do reverse it in those cases, but here I think the posted close reason explains adequately why this question is off topic here. — David Z 45 secs ago
I suppose I should feel bad about that, but I don't

@DavidZ That's somewhat different from your usual (or maybe, I haven't noticed such). Well, I truly like it :D
I can get a lot of wordings from you :P

I think these physics drawings above are made by adobe products. I have been looking at Pearson prentice hall pages, and it seems they are done by Adobe software, but hard to know which. Might be in design or quark express.
I've seen these nice drawings in all Pearson books. They must use the same software. But so far, not able to be sure what is the software.

I think having a skilled artist is more important than the choice of software
e.g. you could make diagrams like that with TikZ (the LaTeX package) if you have the skill to visualize it
 
Nasser

@DavidZ yes, sure. Looking at front of Person books, you'll see dozen folks listed just for publication art. Which includes making these diagrams. They are very nice. I know about Tikz, visio, inkscape, you name it, I tried it. You really need a GUI program to make these things. You can't make autocad drawings using Tickz.
Good 3D drawings, specially for dynamics, help alot. That is why these textbooks by Pearson sell well.
 
David Z
David Z
You don't need a GUI program. It makes it easier, but it's not a requirement. E.g. if I had the time, I'm confident I could closely reproduce either of those figures using TikZ; it would just take a while.
Of course I don't doubt that in practice, these artists do use some GUI program, precisely because it is less time-intensive.

Here is this book if you like to see it. amazon.com/Engineering-Mechanics-Dynamics-13th-Edition/dp/…
@DavidZ, yes, it is the time. I could do this in tickz, or in Mathematica even (which is easier than Tickz), but it will take much more time. For small basic 2-d diagrams, Tikz is fine.
I think they might have used Autocad or Indesign or Quarkexpress now. No way this was done using Visio or inkscape or such program. It must have been a specialized CAD program. The math looks nice also on the diagrams.

@DavidZ It was a bit hash compared to your usual responses but completely appropriate.

When people (mostly feminine) hear a news from the neighborhood, they amplify it on sending the information to others. Right?

Is there any name for that phenomena?

@crazy: gossip, word of mouth, transmission all come to mind
but amplification has got to be the best word for it

@Nick Nice, thanks :)
@Nick: I haven't seen you here... Maybe I don't recall :D

@Nick Oh... fine, I'm a from a blackhole. Nice to meet ya

No, I really am. refererence to the big bang.

Why? Do I look funny? (maybe, but right now...) I'm serious :D

That's how you should remember me. The guy who is random
Why so serious?

Oh...
@Nick I meant, "I was serious in my speech"

I think women are kind of like the hydraulic lift of society, in this model consider a news to be a force exerted on the end of the lift with the smaller piston.
 
Crazy Buddy

@Nick I have a better analogy... What about chain reaction? :P
 
Nick
Nick
The above statement was made to divert the topic to fluid mechanics
I have a test on it tommorrow
and I have no idea what it's all about
 
Crazy Buddy
Crazy Buddy
hehe :D

No, seriously, Volume of object = Volume of Water displaced?
 
Crazy Buddy
Crazy Buddy
@Nick Ooooohhh... Archimedes? :P
 
Nick
Nick
No, archimedes says Weight of object = Buoyant Force
 
Crazy Buddy
Crazy Buddy
@Nick Looks like you're doing good for your exam :D
 
Nick
Nick
Um, except idk if volume of object = volume of water displaced in the case of a floating object
Sure archimedes holds here as well
but volume?
I don't have the tim for experiments!
Neither do I have the time.
@ManishEarth: I choose you, Pikachu. Lightning Strike!
Ok, I should probably set my question straight for somone to attack it.

@Nick: What's your question? o_O

Q: The Atomic/Nuclear Conundrum

TimAssuming that, sans the formation of a black hole, a fission reaction just creates a lot of crap with weird valences flying around at high speed and a lot of heat, the fission reaction is just a blasting cap. However, if a black hole is created, any particle crossing the S-radius gives off energy...

I think that author is schizophrenic. Most confusing, hard to understand wall of text ever.

@crazy: @manish: Consider an object partially submerged in liquid contained in a cylindrical vessel. Will the volume of the water displaced be equal to the vol. of object submerged?
 
Brandon Enright

@Nick for incompressible fluids how could in not be?

@Nick, yes. Provided the liquid is incompressible.
 
Brandon Enright
Brandon Enright
@PranavHosangadi Are there any fluids that are compressible?
 
Pranav Hosangadi
Pranav Hosangadi
@BrandonEnright, I meant to write "yes. Provided the fluid is incompressible". Then I thought I should write "yes. Because liquids are incompressible" Looks like I mixed up the two :P
 
Brandon Enright
Brandon Enright
@PranavHosangadi I wonder what the "most compressible" liquids are. Even water is surely a tiny bit compressible.
 
Pranav Hosangadi
Pranav Hosangadi
@BrandonEnright: of course. The tiny bit is too tiny to bother about in most cases. Check this table of liquid compressibilities: hyperphysics.phy-astr.gsu.edu/hbase/tables/compress.html
