This report is about the optimization of a tie rod, which is a crucial part of a car's steering system. The tie rod is typically made of cast iron, but in this study, we also used aluminum to make the tie rod. We analyzed the performance of the tie rod using different methods such as theoretical calculations, experiments, and computer simulations. We compared the results of the aluminum tie rod with the traditional cast iron tie rod, and evaluated them based on cost and weight. Our calculations showed that aluminum tie rod is a better option as it is lighter and cheaper than the cast iron one. The experiments and computer simulations confirmed these findings and showed that the aluminum tie rod is a good alternative to the traditional one.
