Circumferential stress in a toroidal shell
Consider the following formula for circumferential stress (σ2) in a toroidal shell (taken from Roark's Formulae for Stress and Strain):
It seems that it has been derived by using simple force balance ...

What are the claimed advantages of using Carbon fiber for a pressure hull? [closed]
Much of the news around the Titan incident has focused on all the reasons that carbon fiber was a bad choice for the hull, but I've yet to see any discussion as to why it was chosen at all.
Was it ...

How to calculate the logarithmic mean temperature difference of a jacketed vessel?
I'm a bit confused on how to calculate the $ \Delta T_{LM}$ of a jacketed isothermal CSTR. Because the formula for the logarithmic mean temperature difference is:
$$ \Delta T_{LM} = \frac{\Delta T_{...
