What is Young's Modulus and what does it represent?
Answer
Young's Modulus (E) is the ratio of normal stress to normal strain within the elastic limit, representing the stiffness of a material. It indicates how much a material resists deformation under axial loading - higher values mean stiffer materials. For steel, E is approximately 200 GPa, while for aluminum it is about 70 GPa.
