What kind of bar did you use?
Young modulus works out as Stress/Strain and this example you can calculate it as 0.166 N/mm2. This would indicate that the bar is composed of a mild steel material. The bar is 500mm long and 8mm in diameter.
How did you come up with 3 change in length???
The original length is 500mm and the bar was stretched to 503mm, therefore the change in length is 503 - 500 = 3mm.
The original length is given tin the problem as 500mm and the bar was stretched to 503mm, therefore the change in length is 503 - 500 = 3mm.
