The 4-Mg helicopter maneuvers a horizontal turn having a radius of curvature ? = 400 m as shown in (Figure 1). Determine the lift force FL required when it is flying horizontally with a constant speed of v = 60 m/s .

Determine the angle of the bank ? when it is flying horizontally with a constant speed of v = 60 m/s .

Show that ? increases if v increases by also calculating ? when v = 80 m/s .
