Stress=σ=Force/Area
Strain=ε=σ/E
Change in length = ε*Length.
Useful conversion factors
1 GPa = 10^9 Pa
1 kN = 10^3 N
1 m = 1000 mm
Try to do calculations in standard units, namely kg, m, s.
A steel tube 30 mm outside diameter and 25 mm internal diameter and length 500 mm is subjected to a tensile load of 37 KN, determine the change in length in mm to 3 decimal places when the load was applied. For the material E = 210 GPa.
