Either \propto or \varpropto seems to give the correct symbol. TeX often uses "var" to indicate a variation of a symbol (for example \epsilon ϵ vs \varepsilon ε; \theta θ vs \vartheta ϑ ), so "propto" seems like a reasonable guess as to what this symbol should be called.

Webb10 apr. 2024 · Hooke’s law states that within the elastic extent of a material, the material’s strain is proportional to the material’s stress. The atoms and molecules get a deformation of an elastic material when it gets stretched. It stays stretched for the total time of application of stress. When stress gets removed, they go back to their normal form.
