Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_143

5/143 The disk rotates about a fixed axis through point \(O\) with a clockwise angular velocity \(\omega_0 = 20 \text{ rad/s}\) and a counterclockwise angular acceleration \(\alpha_0 = 5 \text{ rad/s}^2\) at the instant under consideration. The value of \(r\) is \(200 \text{ mm}\). Pin \(A\) is fixed to the disk but slides freely within the slotted member \(BC\). Determine the velocity and acceleration of \(A\) relative to slotted member \(BC\) and the angular velocity and angular acceleration of \(BC\).
