where A is the cross-sectional area of the section (= bd) and J = (bd/\2)(b2 +d2).

5.2. Narrow rectangular sections

From Table 5.1 it is evident that as the ratio d/b increases, i.e. the rectangular section becomes longer and thinner, the values of constants k\ and k2 approach 0.333. Thus, for narrow rectangular sections in which d/b > 10 both k\ and k2 are assumed to be 1/3 and eqns. (5.1) and (5.2) reduce to
