Design a helical compression spring subjected to a varying axial force of 1000 N to 2000 N, is made of circular steel wire. Over this force range, the deflection of spring should be approximately 5 mm. Consider spring index = 5, for the spring that has square and ground ends. The spring is made of patented and cold drawn steel wire of grade 1 with A and m = 1753 and 0.182 respectively. The permissible shear stress for the spring wire should be taken as 50% of the ultimate tensile strength.
