Mechanical Properties of Metals topics include: Stress and strain, tension and compression tests, torsional tests, stress transformation, mechanical properties, design and safety factors. The mechanical properties of metals are related to their ability to resist mechanical forces and loads. These properties include: Strength: A metal's ability to withstand a load before breaking. Tensile strength is a common measure of strength. It indicates a material's ability to absorb energy and withstand stretching before breaking. Stiffness: A material's ability to resist deformation under stress.... Show more
