Question

The engineers wants to examine the steel bar having three sections. So they have applied an axial pull
of P in kN to the steel bar of length 700 mm, 42 cm and 0.8 m which has diameters of 2 cm, 30 mm and 5
cm with a total deformation of 0.51 mm, assume E. For that purpose you are going to help the engineers
by calculating the axial pull, P and stress in all the three sections. Also do your interpretation of results
based on area of cross section, stress and deformation.
