The initial tension is released, when a tension spring is extended to a certain point, where gaps appear between the coils.
The rate is the strength of a spring as defined by Hooke's law. Hooke's Law states that the force needed to extend a spring is directly proportional to the distance you stretch it. Hooke's Law can be represented as F = ks. 'F' is the spring's restoring force 'k' is the spring constant 's' is the deflection (extension)
Counting coils on a tension spring is the same as counting coils on a compression spring. The type of ends on a spring will make no difference to the number of coils.
How spring loads work within a tension spring. If too much weight is applied to the spring it will no longer contract, therefore breaking the spring.
How to measure the length of a tension spring.
How to measure the diameters of a tension spring.
The next video in our Springtelligence series shows you how to allow for tolerances in spring manufacture.
Over the last few months there have been a number of developments at the JB Springs factory in Skipton that have already contributed to improvements in productivity and efficiency, which we expect to continue throughout 2019 and beyond. Improvements to both factory floor operations and our back-office systems and procedures have been made possible through a number of grant funded initiatives. Factory Expansion & Efficiency The JB Springs factory has been expanded by 6,000sq feet which includes a new [...]
This video in our Springtelligence series shows you how to calculate the rate of a compression spring defined by Hooke's Law.
The next video in our Springtelligence series shows you how spring loads work and how it is derived from spring rate.
