Calculating Spring Tension

Various Extension Springs

All springs are constructed to have an initial tension, that force that keeps the coils together in a set position. As a measurement, initial tension is the load or force necessary to overcome the internal force to start coil separation. How to calculate spring tension, and its importance will help to determine how effectively a… Read more »
