Figure 11: Variations in average forces acting on the support plate pin shafts with changes in pitch and roll angles. (a) Mean force along the direction acting on support plate pin shafts corresponding to changes in positive pitch angle, (b) mean force along the direction on support plate pin shafts corresponding to changes in negative pitch angle, (c) mean force along the direction on support plate pin shafts corresponding to changes in positive roll angle, and (d) mean force along the direction on support plate pin shafts corresponding to changes in negative roll angle.
