Question

Does temperature affect spring constant

Answer 1

Yes, the temperature affects the spring constant.

1. Spring constant decreases with an increase in temperature.
2. The definition of spring constant can be got from Hooke's Law, $F=kx$, (where $F$ is force, $k$ is spring constant and $x$ is displacement in length.
3. When the temperature of any material increases then the displacement length $x$ increases and the spring constant $k$ decreases.
4. The unit of spring constant is $\raisebox{1ex}{$N$}\!\left/ \!\raisebox{-1ex}{$m$}\right.$.
