Strain energy (U)(=½(WΔ))
Now, axil deformation due to load W is given by (Δ1=WL/AE)axial deformation due to self-weight W is given by (Δ2=WL/2AE)
(NowΔ1=2Δ2)(and U∞Δ)
Hence strain energy due to load W is given by (U1=(1/2)WΔ1)
(U1=2U2)
Hence strain energy as compared to that due to self-weight will be double.
Hence the option C is correct.
