題目 Problem

The pin \(A\) of the hinged link \(AC\) is confined to move in the rotating slot of link \(DO\). The angular velocity of \(DO\) is \(\omega = 2\ \text{rad/s}\) clockwise and is constant for the interval of motion concerned. For the position where \(\theta = 45^\circ\) with \(AC\) horizontal, determine the angular velocity of \(AC\) and the velocity of \(A\) relative to the rotating slot in \(DO\). Also determine the angular acceleration of \(AC\) and the acceleration of \(A\) relative to the rotating slot in arm \(OD\).
