SUMMARY
The discussion centers on calculating shear stress in a thin-walled pressure vessel subjected to an external force of 40 kN. The participant correctly identifies the formulas for hoop stress (σ=pr/t) and longitudinal stress (σ=pr/2t) but seeks clarification on the application of shear stress (τ=VQ/It) in this context. It is established that the external load generates shear stress, while the internal gage pressure does not contribute to shear stress. The participant is encouraged to reconsider the relationship between external forces and stress types in pressure vessels.
