The document describes the tensile test procedure which is used to determine important mechanical properties of materials. In a tensile test, a specimen with a uniform cross-section is placed in a universal testing machine and loaded until failure. The load and displacement data obtained is used to construct stress-strain curves and extract properties like yield stress, tensile strength, and elongation percentage. Properties such as yield stress, tensile strength, and elongation percentage provide information for comparing and selecting materials for engineering applications.
