Unformatted text preview: a thrust of T = 0.5 N at a radius of 15 cm with respect to the center of gravity. Please find the time required for the vehicle to rotate 45 ° about the center of gravity from a stop, assuming there is no friction. y x y x levitation fan vehicle T T ENES 100 Introduction to Engineering Design Fall 2010 3. Consider the hovercraft with plan (top) view as shown, and with the following properties. The vehicle mass is m = 2 kg. The pressure generated by the levitation fan is Δ p = 100 Pa. The plenum area is A p = 0.15 m 2 . Each propulsor generates a thrust of T = 1 N. The static and kinetic friction coefficients are μ s = 0.3 and k = 0.2 . (a) Show that there is enough thrust to overcome the static friction. (b) How long will it take the hovercraft to travel 1 m? y x levitation fan vehicle T T...
