7. The truss shown is constructed of steel; thus E=29,000ksi. The force carried by each member of the truss under the given loading is provided in the truss figure.
Each member of the truss has the same cross-sectional area.
Using the Method of Virtual Work, find the cross-sectional area needed for each bar if Point B's vertical deflection must be no larger than 1.20 in.
The truss with no load is provided for you below to alleviate the need for you to redraw it.
