66 GRAPHIC STATICS CHAP. positions of tlic force-ti-iangle at G. The net change in the direction of the flight-path relative to the horizon is represented by the difference of angle of MOM' —EDE'. If the machine was originally flying horizontally, and we draw a circle centre 0 and radius OM… … E E Fig. 16. N we see that angle MON=EDE' and the net result of tilting up the 7'ear plane is to cause the machine to rise at an angle NOM'. Thus elevating the rear plane causes the machine to rise, and conversely depressing it causes the machine to descend. 42. Corrections. — The above…
