In (Figure 1), members $$AB$$ and $$BC$$ can each support a maximum compressive force of $$850\mathrm{lb}$$, and members $$AD,DC$$, and $$BD$$ can support a maximum tensile force of $$1500\mathrm{lb}.a=10\mathrm{ft}$$. Determine the greatest load $$P$$ the truss can support. Figure Express your answer to three significant figures and include the appropriate units.
