Question
A typical compound helical spring consists of two coaxial closed coil spring having the following particulars:
Outer spring 1: mean coil diameter = 100 mm
Wire diameter = 12.5 mm
No. of turns = 15
Inner spring 2: mean coil diameter = 75 mm
No. of turns = 20
Both the springs are of equal initial length when unloaded. If
the working stress for each spring is to be same. The modulus of rigidity for the wire material is 80 GPa.
Calculate the following:
a. Diameter of steel wire for inner spring. b. Stiffness of inner spring
c. Stiffness of the compound spring.
I need answer ASAP. Thank you!
