Unformatted text preview: 68 Chapt. 6 Newtons Laws and Dynamics II can exert on the plane (the aerodynamic lift) acts perpendicularly to the wings. Let F lift be the aerodynamic lift magnitude. a) Draw a free body diagam for the airplane in the plane perpendicular to the airplanes instantaneous direction of motion. b) Apply Newtons 2nd law to airplane in the plane perpendicular to the airplanes instantaneous direction of motion. Remember the course mantra: Newtons 2nd law is always true and its always true component by component. c) Solve for the r in terms of the other variables: i.e., in terms of m , , v , g , and F lift . d) Given v = 600 km / h and = 30 , what is r ? 006 qfull 00560 3 3 0 tough math: road banking formula 5. Because road friction is variable with weather (dipping low with rain and especially ice and snow) and because relying on friction for turning at high speeds is hard on cars and car control, civil engineers (who are very polite engineers) dont like to rely on friction (and we mean static...
