Engineering Mechanics - Dynamics Chapter 16 Problem 16-46 The bar is confined to move along the vertical and inclined planes. If the velocity of the roller at A is v A downward when θ = 1 . determine the bar's angular velocity and the velocity of roller B at this instant. Given: v A 6 ft s = 1 45 deg = φ 30 deg = L 5f t = Solution: θθ 1 = Guesses s A 1f t = s B 1f t = ω 1 rad s = v B 1 ft s = L sin θ () B cos φ () L θ () ω B cos φ () L cos θ () s A B sin φ () + = θ () ω v A B sin φ () + = s s B ω v B Find s A B , ω , v B , () = s A s
