Spring constant and temperature

[adam.musial]

Hey!

Does anybody know any possible relationship between spring constant and the temperature of that spring??

 

[Chi Meson]

THe spring constant ,k , is a force constant for a particular spring. The temperature is a measurement of the average kinetice energy of the molecules of the spring. THey are not directly related.

For most things, the "Young's modulus" of the material will change with the temperature, most things getting more easily stretched as temperature increases. Therefore the spring constant will get smaller for most things as the temperature goes up.

Somethings get stiffer as temperature increases, so there is no absolute rule that associates these two characteristics.

They ARE related! The spring is not an ordinary spring but polymers. You can derive Hook's Law by applying statistical methods and take the short displacement limit, the coeff. in the out front is obviously the spring const. and it is proportional to the temperature! I don't know why?!

We can perform a simple experiment to know about the relationship between spring constant and temperature :
STEP1 : Take a rubber and decrease its temperature.(keep it in your refrigerator)
STEP2 : Now drop it on the floor to check its elasticity.
If compared with a rubber at room temperature
the elasticity of the cooled rubber will be less than the rubber at room temperature
it simply means that when the temp is decreased the elasticity is also decreased
the rubber behaves like spring as both are elastic materials

spring constant k is inversly propotional to temperature.

Hello! There is indeed a relationship between spring constant and temperature. The spring constant, also known as the stiffness or force constant, is a measure of how much force is required to stretch or compress a spring by a certain distance. This constant is affected by various factors, including the material and shape of the spring, as well as temperature. In general, as temperature increases, the spring constant decreases. This is because as temperature rises, the atoms in the spring vibrate more vigorously, causing the bonds between them to weaken and making the spring less stiff. This relationship is known as thermal expansion and is a common phenomenon in many materials. It is important to consider the effect of temperature on spring constant when designing and using springs in various applications. I hope this helps answer your question!
