For a new sailboat, a designer wants to determine the drag force that may be expected at a given speed. To do so, she places a model of the proposed hull in a test channel and uses three cables to keep its bow on the center-line of the channel. Dynamometer readings indicate that for a given speed, the tension is 35 lb in cable AB and 40 lb in cable AE. The drag force is exerted in the direction of Flow at point A. -7 ft 1.5 ft B a 4 ft Flow A 4 ft E What is the magnitude of the drag force in Ib? What is the magnitude of the tension force in cable AC in Ib? What is the angle a in degrees measured CCW from the vertical? What is the angle B in degrees measured CW from the vertical?
