Because the distance ycg is less than the half-depth of 5.0 in., the neutral axis is closer to the compression flange and, therefore, the maximum stress occurs in the tension flange. The maximum compressive stress can be computed as follows:

Since the above computed stress is less than the assumed value, another trial is required. • Second approximation. Following several trials, assume that f = 40.70 ksi 1 = 2.682 > 0.673 b = 4.934 in.
