Consider two rods A, B of the same material and subjected to equal axial load. The rod A is of uniform cross-section with diameter d, and the rod B taper uniformly from diameter d at one end to diameter d/2 at other end. The ratio of elongation of rod A to elongation of rod B will be:
1
1 : 1
2
1 : 2
3
1 : 3
4
1 : 4
