Two thin strips of the same material and same cross section are bent by couples of the same magnitude and glued together. After the two surfaces of contact have been securely bonded, the couples are removed. Denoting by σ1 the maximum stress and by σ1 the radius of curvature of each strip while the couples were applied, determine
(a) the final stresses at points A, B, C, and D,
(b) the final radius of curvature.
