When immersed in a uniform stream, a heavy rod hinged at A will hang at Podes angle

Question:

When immersed in a uniform stream, a heavy rod hinged at A will hang at Pode’s angle θ, after L. Pode (1951). Assume the cylinder has normal drag coefficient CDn and tangential coefficient CDt, related to Vn and Vt, respectively. Derive an expression for θ as a function of system parameters. Compute θ for a steel rod, L = 40 cm, D = 1 cm, hanging in sea level air at V = 35 m/s.
