Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index

Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index as 5. The maximum permissible shear stress for spring wire is 420 MPa and modulus of rigidity is 84 kN/mm. Take Wahl's factor, K = 4C-1+ 0.615 4C-4 where C = Spring index. Determine the followings: (a) Mean diameter of the coil (b) Outside diameter of the coil (c) Number of turns of the coils (d) Free length of the spring Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index as 5.
