Tension spring configurator

Loaded length (L1)   ?L1 (loaded length): This is the Length obtained under load P1.
Working deflection (F1)   ?F1 (loaded deflection): This is the difference in height obtained under load P1.
Load (P1)   ?P1 (load at length 1): This is the load required to obtain the length L1.
Stiffness (K)   ?K (stiffness): This is the spring strength during compression, in other words it is the force increase per millimetre of compression. It is measured in N/mm = 0.1DaN/mm.

Conversion : 1 kg = 9.81 N

Loaded length (L2)   ?L2 (loaded length): This is the length obtained under load P2.
Working deflection (F2)   ?F2 (loaded deflection): This is the difference in length obtained under load P2.
Load (P2)   ?P2 (load at length 2): This is the load required to obtain the length L2.
