other ans provides basics on spring constant n why it is affected by temperature. the actual change is more complicated - in addition to microstructural change, the spring itself expands when heated n contracts when chilled.
it depends on the material in question but in general spring constant decreases as temperature rises. so for the same force, the spring will extend more at higher temp.
Converting the measured force into a resultant displacement requires an accurate spring constant. This spring constant may change as the temperature rises due to microstructural effects. As the temperature increases, the spring constant decreases. A linear fit was made to the data to determine the spring constant
Equations!
F = kx. F is the force applied to the spring in newtons (N) k is the spring constant measured in newtons per meter (N/m) x is the distance the spring is stretched from its equilibrium position in meters (m) The Hooke's Law Apparatus.
Effects!
The heat treatment process alters the microstructure and strength of material, which will directly influence fatigue life [2]. Spring manufacturing requires materials
