Engineering Mechanics - Dynamics Chapter 13 *Problem 13-56 The jet plane is traveling at a constant speed of v along the curve y = bx 2 + c . If the pilot has a weight W , determine the normal and tangential components of the force the seat exerts on the pilot when y = y 1 . Given: b 20 10 6 × 1 ft = W 180 lb = c 5000 ft = v 1000 ft s = g 32.2 ft s 2 = y 1 10000 ft = Solution: yx () bx 2 c + = y' x () 2 bx = y'' x () 2 b = ρ x () 1 y' x () 2 + () 3 y'' x () = Guesses x 1 1f t = F n 1lb = θ 1 deg = F
