Is Young's modulus of rubber is greater than steel?

No, Young's modulus of rubber is not greater than that of steel. Young's modulus is a measure of a material's stiffness, and rubber is much more flexible compared to steel. Typically, Young's modulus for rubber ranges from about 0.01 to 0.1 GPa, while for steel, it is around 200 GPa. This significant difference indicates that steel is much stiffer than rubber.
