Oil-tempered wire of 5 mm diameter is used to make a helical compression spring shown in Figu 3. The spring index would be, C= 12. The spring will be operated inside a bore, therefore buckli is insignificant. Both ends are left plain. The spring free length is 100 mm. An axial force of 75 should deflect the spring by 10 mm. a) Determine the spring rate, k. b) Determine the minimum hole diameter for the spring to operate. c) Determine the total number of coils needed. d) Determine the solid length, Ls. e) What force, F's is needed to compress the spring to its solid length? ) Determine the largost shear stross in the spring due to the force Fs. Fs Lo Figure 3 IMw
