If you are designing a product that requires any sort of smart-motion precision, spring parts that apply constant force or constant resistance are key mechanical design elements to consider. Two of ...

The spring constant of a spring can be found by carrying out an experiment. The unloaded length of a spring is measured. Slotted masses are added to the spring. Record each stretching force in N and ...

Constant Force Springs from Lee Spring offer an excellent mechanism for applications where a constant load is required. Some of the many applications of constant force springs are in counterbalances, ...
