Objective Compute the maximum, minimum, mean, and alternating tensile stresses in the flat spring. Compute the stress ratio,Appendix 3 gives the modulus of elasticity for steel to be E = 207 GPa. The moment of inertia, I, for the spring cross sectioThe bending moment is M= P.L = (4.63 N)(65 mm) 301 N.mm o The bending stress at point A is Mc (301 N.mm)(0.40 mm) = 470 N/mm2
