$10\mathrm{.}5.$ A $6060-ft$ homogeneous plate carries a live$-$plus$-$dead load of $100l\frac{b}{f}{t}^2,$ Consequently, the plate has a bending moment of $m=0\mathrm{.}11w{a}^2=0\mathrm{.}11(100)(6060)=40,000ft-l\frac{b}{f}t$ at midspan. A bar system with a depth of $3$fthasmem. bers spaced $4\mathrm{.}0ft$ on center, has a similar self$-$weight, and carries the same uniformly distributed loading. What is the approximate force present in a typical upper or lower chord bar member at midspan?

Answer: $T=C=53,333lb.$
