Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_118

5/118 The mechanism of Prob. 5/90 is repeated here. If the band has a constant speed of 2 m/s as indicated in the figure, determine the angular acceleration \(\alpha_{AB}\) of link AB. (From Problem 5/90: The flexible band F is attached at E to the rotating sector and leads over the guide pulley G. Given values from the figure: \(OA = 0.3 \text{ m}\), \(OE = 0.4 \text{ m}\), \(AB = 0.36 \text{ m}\), \(BD = 0.18 \text{ m}\). In the position shown, \(OA\) is horizontal, and link \(BD\) makes a \(15^\circ\) angle with the horizontal.)
