A Helical Extension Spring Using Stainless Steel Wire With Astm A313 Type 302 And Exert A Force Of 120 Lb At A Length 2 (53.73 KiB) Viewed 34 times
A helical Extension spring using stainless steel wire with ASTM A313, type 302 and exert a force of 120 lb. at a length (Lo) of 10.8 in. The mean diameter is 1.5 in., and the spring rate is 14 lb/in. Let Wahl factor k = 1.25, For an average service design with actual design stress Ta = 80 ksi, Compute: a) The required number of coils in the body of the spring using eq. 18-12
b) The deflection from free length to operating length.
