A cylindrical specimen of a metal alloy 45.3 mm long and 9.72 mm
in diameter is stressed in tension. A true stress of 372 MPa causes
the specimen to plastically elongate to a length of 54.2 mm. If it

calculate the true stress (in MPa) necessary to plastically
elongate a specimen of this same material from a length of 45.3 mm
to a length of 57.6 mm.
