Q2)A concentric spring consists of two helical compression springs having the same free length. The composite spring is subjected to a maximum force of 2000 N. The inner spring's wire diameter and mean coil diameter are 8 and 64 mm, respectively. Also, the outer spring's wire diameter and mean coil diameter are 10 and 80 mm. The number of active coils in the inner and outer springs is 12 and 8, respectively. Assume the same material for two springs, and the modulus of rigidity of the spring material is 81370 N/mm². Calculate: (i) the force transmitted by each spring; and (ii) the maximum deflection of the spring

Kindly answer correctly. Please show all the necessary steps
A helical compression spring is subjected to a maximum force, Fmax of 1250 N. The deflection of the spring corresponding to the maximum force should be approximately 30 mm. The spring index is 6. The allowable shear stress is 350 MPa and the modulus of rigidity is 81 370 N/mm². Design the helical spring by calculating the wire diameter, mean coil diameter, number of active coils and the total number of coils. State all assumptions and decisions in your design.
