A safety valve spring made of oil-tempered chrome vanadium steel having a 9.5 coils has squared and ground ends. The outside diameter is 115 mm and wire diameter is 13 mm. It has a free length of 203 mm. The spring must be initially compressed to hold the boiler pressure of 1.38 Mpa on the valve seat of 32 mm diameter. Determine the spring stress if it is compressed to its solid length.
