Mechanical-strength definition

The ability to withstand the stress of physical forces. Cable and wire systems, for example, must be designed in consideration of the amount of twisting and bending (flex strength) they can tolerate and the amount of weight or longitudinal stress a cable or wire can support (tensile strength) without suffering deformation or breaking (break strength). See also break strength, flex strength, strength member, and tensile strength.
