Sometimes these springs are called torsion springs, motors springs, power springs. Though apparently, Young's Modulus is a way of doing so that applies only to the material and not its shape, where a spring constant value depends on the dimensions of the material. They are good for things that rotate less than 360 degrees. It is supported in equilibrium by two di erent springs of spring constants k 1 and k 2 respectively. [You should get ]. A graph is drawn with load M in kg wt along X axis and extension, l in metre along the Y axis.
