4. A structural steel rod has a radius R of 9.5 mm and a length of 81 cm. A design engincer estimated that the average axial stretching force on this steel rod will be 6.5·104 N t/-10%. What is the average stress on the rod? Will the steel deform permanently under the estimated range of the axial stretching force? (Structural steel's yield strength is approximately 2.5*10* N/m2, beyond this, structural steel will deform permanently.)
