Find the ratio of strain energies stored in bars A and B of the same axial tensile loads. The bar A is of 50mm diameter through out its length, while bar B though of same length as of A but has diameter of 25 mm for the middle one - third of its length and the remainder is of 50 mm . Assume gradual load
