Step 1

When a force F is applied to the single spring, it stretches by an amount s. The relationship between force, stiffness, and stretch is given by Hooke's Law: F = k_T * s. Show more…

Key Concepts

Spring Stiffness

Spring stiffness, or the spring constant, is a measure of a spring's resistance to deformation. It quantifies the relationship between the force applied to the spring and the resulting displacement, as described by Hooke's law (F = k * s).

Series Combination of Springs

When springs are connected in series, the total displacement resulting from an applied force is the sum of the individual displacements of each spring. This configuration results in a lower effective stiffness compared to any individual spring.

Effective Spring Constant

The effective spring constant is the equivalent stiffness of a system that produces the same displacement under the same force as the individual components. For springs in series, the effective stiffness is given by the reciprocal of the sum of the reciprocals of the individual spring constants, leading to the formula 1/k_eff = 1/k1 + 1/k2.
