- USE ASTM A227 SPRING STEEL
Design a helical compression spring for a static load of 470N at a deflection of 40mm with a safety factor of >2.6. The spring must fit within a 50mm hole using ASTM A227music wire. The cross sectional diameter must be rounded up to the nearest 0.5mm. The spring must sit flat in its assembled position. Specify all parameters necessary for manufacture of the spring. Number of turns, Nt- Free length, Lf - Outer Diameter,...
