Final answer:
To determine the force in truss member FE and whether it is in tension or compression, a free-body diagram must be created and the equilibrium equations applied. The force direction depends on whether FE elongates (tension) or shortens (compression). Specific truss details are required for a numerical answer.
Step-by-step explanation:
To determine the force developed in member FE of a truss and identify whether it is in tension or compression, one must first analyze the truss using methods such as the method of joints or sections. However, since the specific truss is not provided in this question, we can outline a general approach:
- Create a free-body diagram (FBD) of the entire truss and also for the specific joint at which member FE is connected.
- Apply the equilibrium equations: Sum of Forces in the x-direction (ΣFx = 0) and the y-direction (ΣFy = 0).
- If member FE is subjected to an axial force causing it to elongate, it is experiencing tension. Conversely, if member FE is being compressed and shortened, it is under compression.
- The magnitude of the force can be determined using the equilibrium equations in conjunction with the known forces and geometry of the truss.
Unfortunately, without the specific details of the truss and the loading conditions, we cannot provide a numerical answer to the force in member FE or whether it is in tension or compression.
