specification of materials. The teaching and learning of tensile testing was based on laboratory experiments used in the Mechanical Engineering Laboratory (CM180) at the City University. The experiment looked at how the microstructure of a material can affect its properties. It also introduced tensile testing and stress-strain curves. It is done by using of a tensile testing machine. Three basic types of materials were used in the experiment. They were a) mild steel (low carbon)‚ b) copper‚ and c)
