PROBLEM:1 A gas engine valve spring is to have a mean diameter of 55 mm. Themaximum load it will have to sustain is 584 N with a corresponding deflection of 7.18mm. The spring is to be made of tempered wire. Since the material is to be subjectedto repeated loading and fatigue must be considered a low working stress of 650N/mm? will be used. Find the size for wire and number of coils used. Take modulus ofrigidity as 0.84 x 105 N/mm? .Assume the spring coil is squared and ground. Takeshear stress Concentration factor as 1.15.
