A simply supported beam has a vertical point load in the center of the beam. Forthe cross section shown, what would be the preferred orientation to minimize the bending stress if a$=$b$?$A simply supported beam has a vertical point load in the center of the beam.

For the cross section shown, what would be the preferred orientation to

minimize the bending stress if $a=b?$

it doesn't matter since $a=b$

a horizontal, b vertical

b horizontal, a vertical
