Question 10.12: With the reverse flange given in Example 10.11, what is the ...

The tangential flange stress at the flange bore of 16,050 psi is controlling. Because t appears in several terms in a nonlinear manner, the easiest way to select the proper thickness is by trial and error. For the initial trial, use a square relationship as follows:

\frac{16,050}{t^{2}}=\frac{17,500}{(5)^{2}}    or    t = 4.8in.

The value of 𝜆 is recalculated as 3.855. Using this, the S_{ T }^{\prime} = 16,900 psi. By successive recalculations, the thickness is approximately t =4.68 in., which gives S_{ T }^{\prime} = 17,500 psi.
