| Abstract: | A new self-made apparatus is used to demonstrate that spring deformation is mainly caused by torsion of wire. The spiral spring deformation formula and coefficient of stiffness are directly derived by dimensional analysis and two-dimensional model of spiral spring deformation mechanism. |

| Keywords: | spring torsional deformation dimensional analysis coefficient of stiffness |
