Oval cross section springs :
i))Places the maximum area of the wire at the point of highest stress
ii)Reduces the solid Height of Springs: Reduction of solid height enables a larger stroke
of a spring. Reducing the mounting height results in decreasing the dimension of the relevant parts,
which saves space and reduces the weight of the parts.
iii) Higher Load (Lower Stress) :This design enables higher loads or reductions in stress without
changing the dimensions of the relevant parts and the mounting height. As a result,
it is possible to design springs satisfying specifications that cannot be realized by
conventional round wires (circular sections).
