P$\mathrm{.}7\mathrm{.}6-$ Determine the forces within each member of the truss below utilizing the method of sections $($denote compressive forces as negative values and tensile forces as positive values$).$ Given the information in the figure above, determine the force within member BD$.$ Report your answer in units of $[$N$].$ Do not report units with your answer. The use of significant figures is not required. Please round your answer to the tenths place.

Cannot be empty

Hint

Make a vertical cut between truss members BD$,\backslash ($ B C $\backslash ),$ and $\backslash ($ A C $\backslash ).$ Then use the method of sections to find the force in truss member $\backslash ($ B D $\backslash ).$ This can be done utilizing your three equilibrium equations $($i$.$e$.$ summation of forces in the $\backslash ($ x $\backslash )-$ and $\backslash ($ y $\backslash )-$direction, and a summation of moments$).$
