[#131] When a closely-coiled helical spring of mean diameter (D) is subjected to an axial load (W), the deflection of the spring ($$delta $$) is given by (where d = Diameter of spring wire, n = No. of turns of the spring and C = Modulus of rigidity for the spring material)
Correct Answer
(D) $$frac{{8{ ext{W}}{{ ext{D}}^3}{ ext{n}}}}{{{ ext{C}}{{ ext{d}}^4}}}$$
