Structural Mechanics

(C) 2 and 0.18 km (D) (2/3) and 17.6 km An aircraft in a steady level flight at forward speed of 50 m/s suddenly rolls by 180 o and becomes inverted. If no other changes are made to the configur ation or controls of the aircraft, the nature of the subsequent flight path taken by the aircraft a nd its characteristic parameter(s) (assume g = 9.81 ms-2) are (A) straight line path with a speed of 50 m/s (B) upward circular path with a speed of 50 m/s and radius of 127.4 m (C) downward circular path with a speed of 50 m/s and radius of 127.4 m/s
