고체역학 (Gere) — Torsion: Problem 3.9-7
3.9-7 Obtain a formula for the strain energy \(U\) of the statically indeterminate circular bar shown in the figure. The bar has fixed supports at ends \(A\) and \(B\) and is loaded by torques \(2T_0\) and \(T_0\) at points \(C\) and \(D\), respectively. Hint: Use Eqs. (3-50a and b) of Example 3-9 to obtain the reactive torques.
