As shown in the figure is an airplane wing. Consider the W1 is fuel weight of tank. con- der the torsional moment in the tip is I and also the weight is W2. center of fuel tank is 1/10 to the wing rib number five is place at L/2 from the wing tip. Please answers this question properly and the model of the geometry as simple as possible. a) calculate the warping at the tip of the wing. b) if the wing geometry at the rear section is considered as show in figure B, calculate the warping in question a (B) L2 10.2.3.2.18
