The outside diameter of the coils of a safety valve spring is 120 mm while its wire diameter is 15 mm. This spring, having 10 active coils has the ends in plain ground, and has a free length of 200 mm. 1. Determine the length (in mm) at which this spring must be initially compressed to hold a pressure of 1400 kPa applied on a 32-mm diameter valve seat. Use a modulus of rigidity of 80 GPa. 2. calculate the spring’s maximum stress induced if it is compressed to its solid length
