Raise to the power 4
Raise to the power 4
(OP)
Area is metre squared
Volume is metre cubed
Sectional Modulus is metre ???
Is it quadrupled? or does that mean multiply by four?
What is the written description (with superscript) for squaring a square?

RE: Raise to the power 4
It's units are therefore length cubed.
RE: Raise to the power 4
Quadrupled means multiplying by four. I don't think there is a written term for it like cubed or squared.
Squared & cubed come from geometrical analogies. The four-dimensional equivalent is a tesseract, but I've never heard of so many meters "tesseracted".
RE: Raise to the power 4
I thought quadrupled meant multiplying by four which was throwing me, I'd come across it on a web site and wasn't sure where they were going.
I've only ever head of "metres to the forth" which is why I'm asking.
Maybe we should invent the concept and give it a new name, it all has to start somewhere

RE: Raise to the power 4
All physical quantities are expressed in terms of BASE/FUNDAMENTAL quantities :
L : Length
M : MAss
T : Time
t : temperature
Then there are derived quantities:
Speed : [L][T]^-1 => L /T => m/s = km/hr = mm/s (No matter which unit system you use dimensional analysis renders itself useful.
Force = [M][L][T]^-2 => M * L / T^2 => Nm/s2
Hope this helps.

I get dimensional analysis, I'm after the name for raising something to the power of four similar to using squared or cubed.

That operation sounds like something that's more fun than you're supposed to have at work. [surprize]

Semi-related, does everybody remember what the third derivative of position is? Hopefully nobody here is too familiar with that term...

EIv''''=p
EIv'''=-V
EIv''=M
EIv'=Int(M)dx
EIv=[more integrals than anyone should care about]+[a bunch of constants]

I’m not sure I know what you mean. I thought that velocity, acceleration and jerk were kinematic quantities, kinematics being the branch of mechanics that studies the motion of a point. I also thought that shear was represented by the off-diagonal components of the stress tensor. Can you elaborate?

I think would be described as "Dynamics"...as opposed to "statics".

After we got off on "fourpled", I was trying to hang on to the levity...bad attempt...back in my hole!
RE: Raise to the power 4
Nice website.
The difference between kinematics and dynamics is that kinematics studies the motion of bodies irrespective of mass, whereas dynamics studies the forces acting on masses in motion. Statics deals with the equilibrium of forces. Velocity, acceleration and jerk are kinematic quantities.

I think we should call it TIMED (not times) as in four timed equals 256

wes616,
Can you give us a phonetic spelling on that one? Is it Tie'med or tie-med' or more like timid? Perhaps tim-ed'?
RE: Raise to the power 4
point
area
volume
time - ^4
So it would be TIMED
Like I timed the race, and that horse had the new track record...

Not sure "timed" would get my vote...doesn't sound technical enough. Trying to explain it would lead to people misunderstanding and thinking ill of you. "Forepled" on the other hand...hmmm...
RE: Raise to the power 4
But I could be convinced of forepled...

A cube is a 3 dimensional object.
A tesseract is 4 dimensional cube object.
Perhaps "meters tessered"
or "Tessic meters"
RE: Raise to the power 4
I assume fourple rhymes with "vorpal" if that helps.

For some reason, those Cro Magnon types in France did not work out second moment of area in their cave paintings.
