In a tensile test of an aluminum rod it has a calibrated length of 50.8 mm and a diameter of12.74 mm. A load of 3 180 kg and an elongation at the elastic limit of 0.0175 cm was recorded. The distance in the areacalibrated after the break is 5.65 cm and the final diameter in the section of the fracture was 1.05 cm.

The distance in the area calibrated after the break is 5.65 cm and the final diameter in the section of the fracture was 1.05 cm. determine :
a) the effort in the elastic limit; b) The elastic modulus ofthe material; c) The ductility of the material ie the deformationunit and the reduction of total area until the test tube ruptures;d) The final length of a bar of this material 250 cm when applyingan effort of 200 MPa.
