Transcribed Image Text:
One of the wings of a Cessna 172 airplane is shown. The wing is supported by a strut BE with ball-and-socket joints at B and E and by bearings at A and F. The bearings are perfectly aligned and are supported by a straight shaft which is fixed to the fuselage, and bearing A is a thrust bearing. Bearings A and Flie on the x axis, point B lies on the y axis, point Elies on the z axis, and points C and D lie in the xy plane. The plane's mass, including fuel, passengers, and cargo, is 1100 kg, and it flies so that it is in static equilibrium. The strut BE has negligible mass and the wing ABCDF has 200 kg mass with center of gravity at point B. The force Q acts in the -x direction and is due to air drag. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 0.1 m B 0.1 m y D 0.6 m 0.3 m 2m 1.4m If the drag force Q is 10% of the lift force P, determine the force supported by the strut BE and the reactions at bearings A and F. (Round the final answers to four decimal places.) (Do not include a minus sign in your response.) One of the wings of a Cessna 172 airplane is shown.
