Stiffness of helical spring

WebFigure 2.4 sketches a helical spring and gives the stiffness equations corresponding to either axial (translatory) motion or to torsion-generated (rotary) motion. The parameters defining the helical spring are the radius R , the wire diameter d , the number of active turns n , and the material shear and Young's modulii, G and E (more details on ...

Suppose I exert a force radially along a certain height of the spring, … WebThe helical torsion resists the bending moment (P x r) that tends to wind up the spring. The bending moment induces bending stresses in the spring wire. The term torsion spring is somewhat misleading because the wire is subjected to bending stresses, unlike torsional shear stresses induced in helical torsion or tension springs.
