This report details two laboratory experiments conducted to determine the mechanical properties of various materials. Experiment 1 focuses on determining Young's Modulus for copper, brass, carbon steel, and stainless steel through tensile testing, comparing experimental values with published data and calculating percentage errors. Experiment 2 investigates the effects of heat treatment and carbon content on the tensile strength and hardness of carbon steel specimens. The experiment involves tensile and hardness tests on different carbon steel samples, analyzing stress-strain graphs and mechanical properties such as proof stress, percentage elongation, fracture stress, ultimate tensile stress, and yield stress. The results highlight the influence of carbon content and heat treatment on the material's mechanical behavior. The report includes detailed methodologies, results, discussions, and conclusions for both experiments, providing a comprehensive analysis of the material properties investigated.
