5 5a 5b 5c Alaterally supported beam was designed for flexure. The beam is safe for shear & deflection. The most economical section is W 8 x 13 however the said section is not readily available at the time of the construction. If you are the engineer in charge of the construction what alternative section will be the best replacement? Why?

A steel plate (called a cover plate) having cross-sectional dimensions W2 8.0 in. x 0.7 in. is welded along the full length of the bottom flange of a W, 12.0 in. x 14.0 in. wide-flange beam (see the figure, which shows the beam cross section). I W2 cover plate What is the percent increase in the smaller section modulus (as compared to the wide-flange beam alone)? Round your answer to two decimal places. % in smaller section modulus =|
