Constant Force Springs

Most springs are bound by the famous principle of Hooke’s law (F=kX), but, as is so often the case, there is usually an exception to even the most widespread rule. Constant force springs represent just such an anomaly. These springs are so named because their force of motion is always at a consistent point of exertion. Resembling a wound coil, their freedom from Hooke’s law allows them to produce perpetual force throughout their deflection. Because the force to restore unrolled constant force springs is nearest the roll, there is almost no restriction upon their speed of extension or acceleration.
