no plagarism answer **Rotational Dynamics of a Two-Arm System**In the system shown in the figure, the OA arm rotates around the O cylindrical joint, and the AB arm rotates around the A cylindrical joint. At an instant \( t \) (time \( t \)), the angular velocity of the OA arm (\( \omega_{OA} \)) is 8 rad/s, and the angular acceleration (\( \alpha_{OA} \)) is 3 rad/s². The angular velocity of the AB arm (\( \omega_{AB} \)) is 6 rad/s and its angular acceleration (\( \alpha_{AB} \))...**Diagram Explanation**The figure shows a double-arm rotational system. Key components and notations include:- Point \( O \): The pivot around which arm \( OA \) rotates.- Point \( A \): The pivot around which arm \( AB \) rotates.- Point \( B \): The end of arm \( AB \).- Lengths: - \( \overline{OA} = 26 \text{ cm} \) - \( \overline{AB} = 20 \text{ cm} \)- Angular positions and velocities: - \( \omega_{OA} \): Angular velocity of arm \( OA \). - \( \alpha_{OA} \): Angular acceleration of arm \( OA \). - \( \omega_{AB} \): Angular velocity of arm \( AB \). - \( \alpha_{AB} \): Angular acceleration of arm \( AB \). - \( \theta \): Angle between \( OA \) and the horizontal axis. - \( \varphi \): Angle between \( AB \) and the extension of \( OA \).**Question**Which of the following vectors is correct?A. \( -2345.33 \,i - 2674.2 \,j \)B. \( -1785.54 \,i - 2118.3 \,j \)C. \( -1436.95 \,i - 1882.9 \,j \)D. \( -2715.12 \,i - 1218.3 \,j \)E. \( -2115.32 \,i - 1945.3 \,j \)

Given:To find:Angular acceleration of AB

In the system shown in the figure, the OA arm rotates around the 0 cylindrical joint, the AB arm rotates around A cylindrical joint. At a instant t (time), The angular velocity of the OA arm, w OA = 8 rad/s,angular acceleration a OA = 3 rad/s2. The angular velocity of AB arm ,w AB = 6 rad/s and its angular acceler
