Please match the following definitions with the correct concepts. The instantaneous load applied to a specimen divided by its crosssectional area before any deformation The change in gauge length of a specimen lin the direction of an applied stress) divided by its original gauge length. The ratio of stress to strain when deformation is totally elastici also a measure of the stiffness of a material. The stress required to produce a very slight yet specified amount of plastic strain; a strain offset of 0.002 is commonly used. The maximum engineering stress. in tension, that may be sustained without fracture. A measure of a material's ability to undergo appreciable plastic offormation before fracture The onset of plastic deformation The instantaneous applied lond divided by the instantaneous crosstsectional area of a lspecimen
