Derive from first principles the bending equation of an unsymmetrical beam where y and z axes are principal, considering an arbitrary moment applied. Discuss the implications of your findings.
💡 Hint: Be sure to think through both load orientations as you work through.
Given a T-shaped beam with specific dimensions, find stress distributions with respect to varying bending moments about the principal axes, and explain how incorrect alignment assumptions change the stress calculations.
💡 Hint: Graph your distributions to visualize impacts clearly.
