SUMMARY
The discussion focuses on applying the virtual work principle to derive equilibrium equations for a continuous mechanical system, specifically a long thin bar fixed at one end and subjected to pressure P at the other end. The user struggles to derive the correct equilibrium equations, particularly emphasizing the importance of considering the neglected third term in their calculations. The user notes that the terms from their equation result in T δu |_0^L = 0, which does not provide a condition on T due to δu(0) = δu(L) = 0. Expert advice is sought to clarify this issue.
