Here's one to ponder. . Maybe it has been covered before and I
missed it.
Assuming a compass of 360 degrees with 0/360 at the top and 90
outboard, where would the net
force be pushing on the front attach fitting? 325?

| Quote: | From "Stress Without Tears" by Tom Rhodes, Chapter 4, figure 6, the direction of the load at the spar attach comes straight in from the spar or in the original question here, 270 degrees. All other loads come into the fuselage at the strut attach fitting.

I think that Ricks answer is correct assuming the lift inboard and outboard of the lift strut is equal.
If the outer half of the wing has more lift than the inner half. The force at the attach point will be less than 270,, and greater than 270 if the inner half of the wing has greater lift than the outer section.
