What is the Young's modulus for meter rule?

Young's modulus is a measure of the stiffness of a material, defined as the ratio of tensile stress to tensile strain. For a typical metal meter rule, such as those made from aluminum or stainless steel, Young's modulus generally ranges from about 70 GPa (for aluminum) to around 200 GPa (for stainless steel). This property indicates how much the material will deform under stress, with higher values indicating stiffer materials.
