dthis angle, they decrease. (Fig 4). If we consider all the distributed pressure to beequivalent to a single force, this force will act througha straight line. The point where this line cuts the chordof an airfoil is called the CENTRE OF PRESSURE. Thus, it will be seen that as the Angle of Attack… … Ftg. ?.
