An extension spring cycles between 10 and 20 N force with a deflection of 15 mm between the force range.
D=12mmwhile the wire diameter is
1.0mm.r_(1)=(D)/(2), and
r_(2)=3d. spring material is ASTM A227 hard-drawn (HD) wire.
S_(ut)=2200MPa,G=80.7GPa,E=198.6GPaa. Using average value of the uncorrected 'empirical' initial shear stress bound, determine the pre-load due to pre-tension. b. Determine stress at body, and Hook locations A, B, under maximum load. c. Does static failure take place at these locations? Why/why not?
