Using strength of materials theory (see Appendix D), the bending stress sq for curved beams is given by σ_θ =–M(r– B)/[rA(R– B)], where A = b –a, B = (b– a)/log(b/a), R = (a + b)/2. For the problem shown in Fig. 8.30, compare and plot the strength of materials and elasticity predictions for the cases of b/a = 2 and 4. Follow the nondimensional plotting scheme used in Fig. 8.31.
