3 24 Points Determine The Factor Of Safety At Closure Ny For A Helical Compression Spring Made From A228 Music Wire 1 (16.5 KiB) Viewed 31 times

3. (24 points) Determine the factor of safety at closure (ny) for a helical compression spring made from A228 music wire (G = 82.7 GPa) of diameter d 3 mm with an outer diameter of OD 24 mm, a free length of Lo = 60 mm, and 12 total coils. The ends of the spring are squared and ground and the torsional yield strength of the wire has been estimated to be Ssy = 848 MPa. Threaded
