An as –wound helical compression spring, made of music wire, has a wire diameter d = 2 mm, an outside diameter of Do = 15 mm, a free length of L = 115 mm, number of active coil Na = 21, and both ends squared and ground. The spring is unpeended. This spring is to be assembly with an initial load of 20 N and will operate with maximum load of 100 N.a) Estimate the safety factor against fatigue failure. b) Check the spring stability
