1) A 20,000-lb airplane with dimensions shown is being catapult from a carrier with a forward acceleration of 3g. (a) Find the tension in the launching cable T and the wheel reaction R1 and R2 (b) Find the horizontal and vertical shear in the fuselage at cross-section AA and BB and if the portion forward of AA weighs 3,500 lbs and the portion aft of BB weighs 2,000 lbs (c) If the flying speed is 80 mph, what distance is required to gain this speed? How much time is required? 30 A w=20,000 lb R -100----- -40% B B 200----- R 2) If an airplane with the same dimensions as in problem 1 above is taxiing, what is the maximum braking force that can be applied to the front wheel without the airplane nosing over? 1) A 20,000-lb airplane with dimensions shown is being catapult from a carrier with a forward acceleration of 3g.
