How to calculate deflection in beam at orientation?
(OP)
Lets say a hollow rectangle beam of 3" x 5"x 1/4" thk., 48" long is fixed at two ends. This beam is part of attachment of lifting device. If attachment rotates at 20, 30, 45, 60 degree, this beam will also make angle respective angle and Uniformity distributed load will always be right angle to beam.

(e.g. use geometry (sin and cos) to separate the resultant load into components acting in the beam strong and weak axes, compute the deflection due to each, and combine).
With a hollow rectangular shape, torsional deflection should be negligible, so no second order effects to speak of (presuming you don't need accuracy to less than 1/10").

Major and minor axis deflection can be calculated separately using the above loads but the resultant deflection will be the vector sum of those two deflections.

Even I am confuse honestly. But what you referred as deflection would be the same even if the hollow rectangle pipe would be orientated and in the condition of load normal to pipe, make sense to me,too.

The factor 5/384 applies when the supports are hinge and roller. If the ends are fixed as stated in the OP, that should be 1/384.
