Tensile Strength, the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. For example, if a metal rod one square inch in cross section can withstand a pulling force of 1,000 pounds but breaks if more force is applied, the metal has a tensile strength of 1,000 pounds per square inch.
