A spring is known to be made from music wire, ASTM A228 steel, however no other data are known. Using simple measurement tools, the following features are measured. Free length of the spring was 44.45 mm. Outside Diameter was 14.25 mm Wire diameter was 1.4 mm The ends are squared and ground The total number of coils was 10.0 spring will be used in an application where the normal operating load is to be 62.28 N. (Take 1 inch = 25.4 mm) a) Determine the inside diameter, spring index and Wahl factor. b) Determine the expected stress at this operating load. c) Determine the spring deflection at the normal operating load. d) Determine the operating length, solid length and the spring rate.. e) Determine the coil clearance and check the spring against buckling. hole diometer for the spring to operate in.
