Problem 1 Shown in the figure is a 12-gauge (0.1094-in) by 3/4 in latching spring that supports a load of F 3 lbf. The inside radius of the bend is 1/8 in. Estimate the stresses at the inner and outer surfaces at the critical section. -in R. Problem 2 Determine the maximum tensile and compressive stresses acting on section a-a of the curved beam shown. لم Section A-A No. 12 gauge (0.1094 in) 300 lb 1.0 in. 0.75 in. -1.0 in.
