Question

Transcribed Image Text: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.
