# Spring Coefficient Calculator v1 Price: £17.33 (£17.33 Inc. VAT) ## Subject

A spring coefficient is the force required to deflect (or deform) an elastic structural element or body by a unit length (1.0 metre, inch, etc.) and is used to define an expected deflection due to a given load and/or its natural frequency.

A spring coefficient describes a linear relationship between force (F) and deflection (y); i.e. F ∝ y

## Calculator

Spring Coefficient calculates this property for a number of structural elements including; columns, shafts, springs, tensile cords and beams & plates with various end/edge support conditions.

The spring coefficient calculator is not limited to plain or singular elements. Quite complex structural frames such as bridges or crane booms may be calculated with equal accuracy if its material(s) and sectional properties are known, consistent and obey Hooke's law.
