Question
At the instant shown, link \(CD\) rotates with an angular velocity of \(\omega = 7.5 \, \text{rad/s}\). If it is subjected to a couple moment \(M = 300 \, \text{N}\cdot\text{m}\), determine the magnitude of the angular acceleration \((\text{rad/s}^2)\) of link \(CD\). The block has a mass of 50 kg and center of mass at \(G\). Neglect the mass of links \(AB\) and \(CD\). (Hint, since the mass of link \(AB\) or \(CD\) is negligible, the external force or moment acting on it sums up to 0.)

Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take \(g = 9.81 \, \text{m/s}^2\).

**Diagram Description:**

The diagram shows a system with two links \(AB\) and \(CD\). The link \(CD\) is depicted horizontally and attached at ends \(D\) and \(C\). It has an applied moment \(M\) at the pivot \(C\) and is shown to rotate counterclockwise with angular velocity \(\omega\). The distance from \(D\) to \(B\) is 0.1 m, and from \(D\) to \(A\) is 0.6 m. The vertical distances from the horizontal line through \(CD\) to center of mass \(G\) are labeled as 0.4 m.
