Meriam, Kraige & Bolton — Introduction to Three-Dimensional Dynamics of Rigid Bodies: Problem 7_18

7/17 The wheel rolls without slipping in a circular arc of radius R and makes one complete turn about the vertical y-axis with constant speed in time \(\tau\). Determine the vector expression for the angular acceleration \(\vec{\alpha}\) of the wheel and construct the space and body cones. 7/18 Determine expressions for the velocity \(\mathbf{v}\) and acceleration \(\mathbf{a}\) of point A on the wheel of Prob. 7/17 for the position shown, where A crosses the horizontal line through the center of the wheel.
