Just found this forum--hope there isn't a max post limit haha.
I have been a bit stumped on this, but when doing problems about deflection and axial loadings, I am confused when to use which equation.
I think I know that axial member need to be 2 force members, loaded only at the ends, and...

Hi All,
Say we have a legacy database that is not well-documented and we want to reverse-engineer it.
I am looking for an effective way of doing it. Only way I can think is using something like ERwin to
produce a Conceptual, Logical model for the database from which we can reconstruct the...

Should one focus on just the ability to DO the math or also the theory behind it? Would a the book " ISBN-10: 0521679710 " suffice or should I do something to the effect of Spivak's or Apostol's calculus?
I’m thinking about getting this monster of a book because I heard it was incredibly awesome and useful, but I have one question. I want to be both a physicist and a mathematician in the future, so can aspiring pure mathematicians learn many useful things from this book, or does this book only...

Hi all,
New poster here. I'm wondering if anyone can help identify this obscure equipment label.

Hi
I get the impression that most engineering is done with computer; CAD, numerical simulations etc. After all this is done, actually making something starts, and even a lot of that is now done with 3D printers.
How much of engineering is making something with your hands? I reckon this varies...

Hi guys.
As you may know there is a big distinction between Science and Engineering.
Richard Feynman said that Science doesn't have a target, like Engineering has.
Science is about studying the universe, and you can do it by focalizing your attention on the Biology, on the Chemistry, on the...
