A prismatic bar has a cross-section of 25 mm by 50 mm and a length of 2000 mm. Under an axial load of 100 kN, the measured elongation of the bar is 2mm. The tensile stress and % strain in the bar are

• A. 80 MPa and 0.1%
• B. 0.08 GPa and 1.0%
• C. 80 N/mm2 and 1%
• D. 800 MPa and 0.01%
• E. 8 kN/mm2 and 0.001%
