1.The slope distance and zenith angle measured from point P to pointQ were 1876.253m and 87.33'24 degrees, respectively. The instrumentand rod target heights were equal. If the elevation of point P is227.965m, above datum, what is the elevation of point Q?
2.Four forces act on a small airplane in flight: its weight (24kN), the thrust provided by the engine (10 kN), the lift providedby the wings (23 kN), and the drag resulting from its motionthrough the air (3 kN). Determine the resultant of the four forcesand its line of action with respect to the axis of the plane. Thetail of the plane is 10 degrees below the x-axis.
