A bar of length L and cross-section area A is subjected to a gradually applied load P. Another bar of the same material, having the same length L, and cross section area 2A is also subjected to a gradually applied load Q. If the strain energy stored in the two bars are the same, then the ratio \(\frac{P}{Q}\) is:
1
\(\frac{1}{\sqrt2}\)
2
√2
3
\(\frac{1}{2}\)
