Engineering Mechanics - Dynamics Chapter 13 The arm is rotating at the rate θ ' when the angular acceleration is '' and the angle is 0 . Determine the normal force it must exert on the particle of mass M if the particle is confined to move along the slotted path defined by the horizontal hyperbolic spiral r = b . Given: ' 5 rad s = '' 2 rad s 2 = 0 90 deg = M 0.5 kg = b 0.2 m = Solution: θθ 0 = r b = r' b 2 ' = r'' b 2 '' 2 b 3 ' 2 + = tan ψ () r r d d = b b 2 = = atan () = 57.518 deg = Guesses N P 1N = F 1N = Given N P sin () M r'' r ' 2 () = FN P cos ψ + Mr θ 2 r' θ + () = N P F Find N P F , () = N P F 0.453 1.656 N = Problem 13-109 The collar, which has weight W
