A tapering bar (diameter of end sections being, d1 and d2) and a bar of uniform cross-section ‘d’ have the same length and are subjected the same axial pull. Both the bars will have the same extension if ‘d’ is equal to
1
\(\frac{{{d_1} + {d_2}}}{2}\)
2
\(\sqrt {{d_1}{d_2}} \)
3
\(\sqrt {\frac{{{d_1} + {d_2}}}{2}} \)
4
\(\sqrt {\frac{{{d_1} - {d_2}}}{2}} \)
