Another definition would be: The amount of force it takes to compress the spring 1-inch and is expressed in ld/in. The lower the rate, the softer the spring There are many measurements for a springs, and one of the most important aspects of spring design is length. The length of a spring affects its performance and which applications and devices it can be used in, but there are many methods that can be used to determine the height of a spring Calculator Use. This calculator finds the missing variable in the physics equation for Hooke's Law F s = -kx, when two of the variables are known.. Hooke's Law states that the force needed to extend or compress a spring is directly proportional to the distance the spring is stretched or compressed The only thing that will change will be the length of the wire used to wind the spring. The longer the wire is the lower the spring rate. As the wire get shorter, such as when cutting the coil, the spring rate increases. So everyone has a clear understanding lets describe what rate is

Compression Spring Stress. The dimensions, along with the load and deflection requirements, determine the stresses in the spring. When a compression spring is loaded, the coiled wire is stressed in torsion. The stress is greatest at the surface of the wire; as the spring is deflected, the load varies, producing a range of operating stress. Stress and stress range govern the life of the spring Spring Stretch-Extension: The stretch of an extension spring is always ½ the door height . Spring Length: Multiply the wire diameter by the total number of coils in the spring . Wire Size: Measure a length of the spring, then divide by the number of coils within that length
