Final answer:
To determine the load in member GH using the method of sections, draw a free-body diagram of the entire structure and determine the support reactions. Then, isolate the section containing member GH and draw a free-body diagram of that section. Finally, use the equilibrium equations to solve for the unknown forces, including the load in member GH.
Step-by-step explanation:
The method of sections can be used to determine the load in member GH. First, draw a free-body diagram of the entire structure and determine the support reactions at points AAA and EEE. Next, isolate the section containing member GH and draw a free-body diagram of that section. Use the equilibrium equations to solve for the unknown forces in the section, including the load in member GH.
