SUMMARY
This discussion focuses on calculating the bending moment for a wing spar in an airplane design, specifically under a point load of 490 lb. The calculation method involves using the formula for bending stress, σ = My/I, where M represents the bending moment, y is the distance from the neutral axis, and I is the moment of inertia. The user is advised to assume a simply supported beam configuration at the wing tips, with the load applied at the center, and to seek closed-form solutions based on their specific geometry.
