Wood Pole Loading Questions

sonar23: Maybe you could use superposition. (1) Apply your equipment with moment arm, without the wires attached. Compute pole transverse deflection at guy wire attachment point due to this applied moment M. (2) On a separate cantilever, with no wires nor equipment attached, compute applied transverse shear force V at guy wire attachment point required to deflect cantilever the same transverse distance computed in item 1. This will convert M in item 1 to an equivalent transverse shear load V. (3) Now solve your original problem, with wires attached (but without moment-inducing equipment attached), except also apply additional transverse shear load V to pole at guy wire attachment point.

The concept above is, convert the applied moment to a simpler force (neglecting the insignificant transverse shear and moment at pole base) to keep the problem statically determinate. Hope this idea works. The guy wire tension established in this manner will be slightly conservative if the pole has significant bending stiffness and completely solid rotational constraint at the ground.
