NCEES 2008 Solution 525

Does anyone know where they came up with this formula to solve for cylinder thickness? It's more direct than the one I used from the MERM.

Never seen that one before. That one's definitely getting added to the margins.

Check on MERM 51-4. Section 5 describes the equations for Thick Walled Cylinders. I tried first to use the thin walled cylinder equation and then check if t/R < 0.1. From table 51-2 you select for internal pressure the circunferential stress equation calculation.

Hope this helps.
