(a) Draw the influence diagram for the force in member C. Plot tension as a positive value. Label the diagram and define the ordinate values at 6-ft. intervals along the span of the truss.
(b) Draw the influence diagram for the force in member DH. Plot tension as a positive value. Label the diagram and define the ordinate values at 6-ft. intervals along the span of the truss.
Free-body diagrams are a necessary part of your solution. Be sure to present all information necessary to write the equilibrium equations, including the unknown forces and the critical dimensions.
