Parallel And Series Connection Of Tension Springs

Stiffness coefficient, also known as stubbornness coefficient (elasticity coefficient). It describes the magnitude of the elastic force generated by the unit shape variable. A large value of k indicates that the force required per unit length of deformation is large, or the spring is "tough". Stiffness coefficient, also known as stiffness coefficient or stubbornness coefficient. The stiffness coefficient is numerically equal to the spring force per unit length when the spring is extended (or shortened).
Among them, F is the elastic force, k is the stiffness coefficient, and △ x is the spring form variable
