Note: Theoretical method to calculate spring constant: $k_t=\frac{G{d}^4}{8n{D}^3}$

Where, $G$ is the modulus of rigidity $(\frac{N}{m^2})$ of the spring material, $d$ is the wire diameter $(m),n$ is the number of coils, and $D$ is the mean diameter $(m)$ of the spring $($i$.$e$,D=$ outer diameter of the spring$-$wire diameter$).$
