whoa

new tard.  carlson you need some new letters

Here’s another one: F = MA (force equals mass times acceleration) This is a fundamental law of physics, described in the most simple of all mathematical equations, that I use in my work creating finite-element analysis computer simulations of transient nonlinear dynamic systems. (All that means simulating real-life stuff, like cars crashing and figuring out how to design them so that they absorb the energy of impact and protect the human occupants.)

But here’s something very interesting about such a simple mathematical equation as F = MA. Force (e.g., lbf, or pound force) = Mass times Acceleration. Acceleration could be something like feet per second per second (ft. / sec.^2). Solving for Mass with simple algebra we get:

lbf / (ft. / sec.^2) or (lbf times sec.^2) / ft.

Thus, we calculate mass density by dividing mass by volume (in this case ft.^3), and we get:

lbf sec.^2 / ft.^4

How interesting! The simple equation F = MA leads to the concept of four-dimensional space.

And all of this ultimately comes from 1 apple plus 1 apple equals 2 apples


did you get the pathetic part?

poor frill don't know how much of a tard he is.

not yet that is.  until now

I have heard about these simulations on the interwebs. The rumour is you introduce an additional element of reality by having the computer running the simulation experence a similar enviroment to that being simulated!

It’s an interesting idea but I think it will have limited pratical use to be honest.


hahahaha

now he knows

This is a completely incoherent comment, and I have no idea what you are talking about. I’ve just finished a set of FEA simulations at work, the validity of which have been empirically verified through actual physical tests of the systems in question.

If you think FEA has limited practical use I would suggest that you investigate LS-DYNA, the FEA program I use.

P.S. LS-DYNA was originally developed in the early 1970s at Lawrence Livermore National Laboratory, by some of the world’s most brilliant and innovative scientists, primarily for the development and simulation of nuclear weapons.

It works, but you must know how to use it. This is a nontrivial exercise that requires a lot of dedication and effort.


that makes me feel kinda bad for the little guy.  

lololololol just for a second, he's a chump

I take it you don’t throw your computers running the FEA simulations out the back of planes then?
