Find percentage elongation of a steel rod, when it is subjected to an axial pulling force of 50 KN whose diameter is 30 mm and it is 3 meters long. Take E= 200 X 10^9 Newton per meter square. A = π*30^2/4 = 706.5 mm2 ΔL = (P*L)/ (A*E) ΔL = 50*1000*3*1000/ (706.5 *200*10^3) = 1.0616 mm Elongation = (ΔL/L) x 100 = (1.0616/3000)*100 = 0.0354%

Definition. The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
