Question

appropriate significant figures. Score your HW per the Syllabus. [1] The aircraft at right weighs 16,000 lb and isz travelling at 120 mph when it touches down for a landing. If x,-80". x2-30". h 50", and the pair of main landing gears apply 10 kips of braking force on the ground, determine the following: (a), the horizontal acceleration of the aircraft, (b) The reactions on the nose gear (RN)and on the pair of MLGs (RMIG), and (c) the stopping distance of the motion aircraft. 12] The aircraft at right weighs 12.000 lb and is travelling at 100 mph when it touches down on an aircraft carrier and simultaneously makes contact with a hook that applies a force T to a point d-20" below the aircraft cg. The line of the cable applying force T makes an angle of 0-20 with the deck of the carrier, as shown. If the landing gear touches the deck a horizontal distance of x=30" forward of the cg, determine the following: (a) Force T, (b) Force R, (c) the acceleration of the aircraft (assuming it is uniform), and (d) the stopping distance of the Cg aircraft.
