Problem #$3$:

A W $21$ X $68$ of A$992$ steel is used as a simply supported beam with a span length of $50$ feet.

The only load in addition to the beam weight is a uniform live load. If lateral support is provided

at $10-$foot intervals, Use ASD to determine the maximum service live load, in kips$/$ft$,$ that can be

supported?

Problem #$4$:

The beam shown in the figure is laterally braced only at the ends. The $30-$kip load is a service

live load. Use the ASD method to determine whether a W$14$ X $38$ is adequate. $F_y=50$ksi.
