Solution:

A steel bar with a square cross-section of 40 mm × 40 mm is subjected to an axial compressive load of 200 kN. If the length of the bar is 2 m and the Young's modulus (E) is 200 GPa, calculate the elongation of the bar (in mm).

1.25

2.70

4.05

5.40

Solution:

Two bars, one with a circular cross-section and the other with a rectangular cross-section, have the same length L and the same cross-sectional area. They are subjected to the same load P respectively. The Young's modulus of the circular bar is twice that of the rectangular cross-section bar.
