Calculating Stress Energy Tensor for Rotating Bodies

[fobos3]

Hello, can someone explain to me how to calculate the stress energy tensor. If we remove the first row and column, we get get the stress tensor, which I am not familiar with, or am I missing something here? But what about the components of the first column and row. What I know so far is that $$T^{ab}=\texttt{pressure for (a,b) \in (1,3)}$$. Everything else is pitch black. I am interested in the stress-energy tensor of a rotating body.
Any feedback will be appreciated.

The http://en.wikipedia.org/wiki/Stress-energy_tensor" has a figure that describes each component of the tensor.

Maybe Eq 11 or thereabouts.
