What happens to the buoyant force acting on the airship as it rises in the air? Does it increases or decreases? Explain
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.

Consider a blimp that can be approximated as a 3-m diameter, 8-m long ellipsoid and is connected to the ground. On a windless day, the rope tension due to the net buoyancy effect is measured to be 120 N. Determine the rope tension when there are 50 km/h winds blowing along the blimp (parallel to the blimp axis).
