A Mercedes Benz gas engine valve spring is to have a mean diameter of 3.81 cm. The maximum load it will have to sustain is 45.45 kg with corresponding deflection of 1.27 cm. The spring is to be made of tempered steel wire. Since the material is to be subjected to repeated loading, and fatigue must be considered, a low working stress of 2820 kg/sq.cm will be used. Determine the size of wire.
