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 ...

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, ...

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 ...
