Torque (also called moment — mostly by engineers) is calculated by multiplying force and distance. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters).Spring rate is the constant return torque provided per unit of angular displacement. Simply, it is the consistent attempt of the spring to return to its normal shape. Planet Spring offers an automated calculator to determine spring rate; Maximum deflection is the total degree rotation a torsion spring can assume.The Meaning of Torque .
