![11.4 (A/B). Compare the strain energies of two bars of the same material and length and carrying the same
gradually applied compressive load if one is 25 mm diameter throughout and the other is turned down to 20 mm
diameter over half its length, the remainder being 25 mm diameter.
If both bars are subjected to pure torsion only, compare the torsional strain energies stored if the shear stress in
both bars is limited to 75 MN/m².
