A steel plate (called a cover plate) having cross sectional dimensions 6.0 in.× 0.5 in. is welded along the full length of the bottom flange of a W12×50 wide flange beam (see figure, which shows the beam cross section).
What is the percent increase in the smaller section modulus (as compared to the wide-flange beam alone)?
