A typical tensile testing setup - the metal bar will be pulled apart, and the amount of force required to do so will be recorded by a computer throughout the test.

Definition: Strength is a measure of how well a material can resist being deformed from its original shape. Typically, metals are specified for their tensile strength, or their resistance to being pulled apart, but compressive strength is also a legitimate material property describing resistance to being squeezed. Strength is measured in units of pressure, and is typically reported in units of ksi, or "thousands of pounds per square inch."
