  Practical Logbook Entry: Tensile Test Date: Name: Lab Partner(s): Instructor: Objective: To determine the tensile strength, yield strength, and elongation of a given material. To understand the stress-strain behavior of the material under tensile loading. Apparatus: Universal Testing Machine (UTM) Extensometer Specimen (e.g., mild steel, aluminum) Vernier Caliper/Micrometer Ruler/Scale Theory: The tensile test is a fundamental mechanical test where a sample is subjected to a controlled tension until failure. The data obtained is used to calculate material properties such as: Ultimate Tensile Strength (UTS): The maximum stress the material can withstand. Yield Strength: The stress at which the material begins to deform plastically. Elongation: The measure of ductility, calculated as the percentage increase in length before fracture. Modulus of Elasticity (Young’s Modulus): The ratio of stress to strain in the elastic region of the stress-strain curve. Procedure: Preparation of Spe
