If you really want a Mac, Parallels is a program that cost $50 or so and you can run Windows through that.
I would ask your college if they allow remote access to their computers, such as ssh or desktop sharing. If so, like others are saying, you don't need a fancy laptop (you're working on...
Chestermiller,
Do you mean the hydrostatic pressure, ## p ## ?
## p = −\sigma/3 ##
I know that the deviatoric tensor is indeed pure shear, because the sum of the diagonal = 0, but my assignment says that there are two states of pure shear. I am either misunderstanding the wording of the...
Homework Statement
I am having trouble decomposing a uniaxial compressive stress into hydrostatic and pure shear components.
Homework EquationsThe Attempt at a Solution
I am starting with
##
\begin{pmatrix}
-\sigma & 0 & 0 \\
0 & 0 & 0\\
0 & 0 & 0
\end{pmatrix}

Tried to use:
##
t^{\alpha} = \frac{1}{2} \sigma_{ij} (m_{i} n_{j} + m_{i} n_{j})

To find the critical radius, you take \frac{ d\Delta G}{dr} = 0 and solve for r. The reason that I am concerned is due to the fact other solutions that I have found (homogeneous nucleation) are much more simple.
Homework Statement
A cylindrical pill-like solid cluster of radius r nucleates from the vapor phase on a dislocation that emerges from the substrate. The free-energy change per unit thickness is given by
\Delta G = \pi r^2 \Delta G_v + 2 \pi r \gamma + A - B lnr
Where A - Blnr represents...

I understand that decarburization happens during heat treatment of steels @ 700 C, and that carbon reacts with oxygen or hydrogen that is in the atmosphere. But, where does the carbon go?
Homework Equations
None

Does the carbon react with the...
Homework Statement
I am just a little bit confused. I have a question that is asking me to explain what the physical significance of volumetric flux is.
Homework Equations
I am not sure that this problem requires any equations!
The Attempt at a Solution
I know that the flux corresponds to...

If \sigma_{ij} = \begin{pmatrix}
3 & 3 & 3 \\
3 & 3 & 3 \\
3 & 3 & 3
\end{pmatrix} represents a stress tensor, on what plane(s) will the normal stress be a
minimum? On what plane(s) will the shear stress be a maximum?

One more quick question: Would there be a V^N term in front of everything? I know that in the classical monatomic gas solution, there is. And , considering that the pressure is a partial wrt V, I assume it needs to be there again?
Ahh, I was forgetting the (-) in front of the ∞. That would explain a lot! This is still a huge ℤ, so I thought that I was doing it wrong but it sounds like I was on the right track. Thanks!
I don't understand the ∞ in the piecewise. I feel like that would just cause the whole thing to go to ∞.
I don't know how to generate equations in this forum, so I will just try to explain my thought process.
The container is spherical, thus need to use spherical coordinates for V(r).
