4. The cross sections of two solid bars made of the same material are shown here. The square cross section has the bending rigidity \( I_{1} \), and the circular cross section has bending rigidity \( I_{2} \). Both sections have the same cross-sectional area. What is the ration of \( \mathrm{I}_{1} / \mathrm{I}_{2} \).
Expert Answer
Since both section have equal area A1=A2
