A manufacturing plant produces steel rods with a diameter of $50$ mm and a length of $2$ meters. The steel rods are subjected to a tensile test to determine their mechanical properties. Assume the following details:Young's modulus for the steel material is $200$ GPa.The ultimate tensile strength $($UTS$)$ of the steel is $400$ MPa.The yield strength of the steel is $300$ MPa.Tasks:Calculate the maximum load that the steel rod can withstand before reaching its yield strength.Determine the stress in the steel rod when it reaches its yield strength.Calculate the strain in the steel rod at the yield point.Discuss the significance of Young's modulus in relation to the stiffness of the steel rod.Propose methods to improve the mechanical properties of the steel rods, considering both material selection and manufacturing processes.
