1- A helical compression spring is to be made of oil-tempered wire of 4-mm diameter with a spring index of C = 10. The spring is to operate inside a hole, so buckling is not a problem and the ends can be left plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. (a) Determine the spring rate. (b) Determine the minimum hole diameter for the spring to...

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...
