Meriam, Kraige & Bolton — Introduction to Three-Dimensional Dynamics of Rigid Bodies: Problem 7_120

7/120 Determine the angular acceleration \(\boldsymbol{\alpha}\) for the rolling circular disk of Prob. 7/119. Use the results cited in the answer for that problem. Reference from Prob. 7/119: The circular disk of radius \(r\) is mounted on its shaft, which is pivoted at \(O\) so that it may rotate about the vertical \(z_0\)-axis. The disk rolls at constant speed without slipping and makes one complete turn around the circle of radius \(R\) in time \(\tau\). The coordinate axes \(x\)-\(y\)-\(z\) rotate around the \(z_0\)-axis with the shaft.
