Exactamente, we are almost on same wavelength! Refer to prior post on loads with change of angle of line.
On a bell crank other factors change. the angles of input and output change as well. More math than I can figure out tonite but I think principle remains the same as both angles change uniformly at least on a 90 degree bellcrank.

Where would you get the load on the scale if it were as pictured at about 90 degrees?? Would it not just load the bellcrank mounting bolt?
