width b = 5 in

The simply supported beam shown below carries its own weight, a uniformly distributed live load
of 300 lbs/ft, and a concentrated dead load PD at midspan. The cross-section of the beam is U-
shaped. It has two rows of reinforcing bars at the bottom. The bottom row has five #6 bars and the
top row has three #6 bars. Let f =4,000 psi and f, = 60 ksi. The cross-sectional area of a #6 bar
is 0.44 in.².
