For planar convex bodies K with positive area A(K), boundary length L(bd K) and second-order chord power integral I2(K), we study the ratio L(bd K)I2(K)/A(K)*A(K) and give reasons supporting the conjecture that its uniform lower bound is 32/3 attained exactly for circles. In particular, using the Ambartzumian-Pleijel representation of I2(K) we derive formulas for I2(K) in case of general triangles, rectangles, and regular N-gons. In these cases and for ellipses we can prove this inequality. A related conjecture is formulated for the class of convex N-gons which exhibits a strengthening of the isoperimetric inequality as well as of Carleman's inequality for convex N-gons. An extension to higher dimensions is discussed at the end of the paper...
