Find the veocities VA, VB, Vbox, and accelerations aд, ag, abox for the mechanism shown below. Link 2 (Line joining O24) is oriented at 60° in the global coordinate system at the instant shown in the figure, and is rotating clockwise with an angular velocity w₂ of 30 rad/sec. (Hint: This is a parallelogram linkage, which exactly duplicates the rotary motion of the driver crank at the driven crank).

Hello, I'm having difficulty undertanding this kinematics equation. A step by step answer would be appreciated. Thank you.

### Analysis of a Parallelogram Linkage Mechanism #### Problem Statement: Find the velocities \( v_A, v_B, v_{\text{box}} \) and accelerations \( a_A, a_B, a_{\text{box}} \) for the mechanism shown below. Link 2 (Line joining \( O_2A \)) is oriented at 60° in the global coordinate system at the instant shown in the figure, and is rotating clockwise with an angular velocity \( \omega_2 \) of 30 rad/sec. (Hint: This is a parallelogram linkage, which exactly duplicates the rotary motion of the driver crank at the driven crank). #### Diagram Description: The given diagram represents a four-bar linkage mechanism known as a parallelogram linkage. Key elements and details include: - Two fixed pivots labeled \( O_2 \) and \( O_4 \). - Link lengths are provided as follows: - \( L_1 = 150 \) - \( L_2 = 30 \) - \( L_3 = 150 \) - \( L_4 = 30 \) - Link 2 (\( O_2A \)) and Link 4 (\( O_4B \)) are equal in length. - Links 1 (\( O_2O_4 \)) and 3 (\( AB \)) are equal in length. - Angles and directions: - Link 2 (\( O_2A \)) is oriented at 60° with the horizontal (X-axis). - The angular velocity \( \omega_2 \) of Link 2 is given as 30 rad/sec in the clockwise direction. - The system displays a parallelogram linkage which ensures the angular velocity and accelerations are mirrored in the driven crank as well. **Coordinate System:** - The global coordinate system includes an X-axis (horizontal) and a Y-axis (vertical). - The box is connected to the linkage via a vertical link extending from point A, replicating the rotary motion into linear motion. #### Solution Requirements: To determine: - Velocities \( v_A \), \( v_B \), and \( v_{\text{box}} \). - Accelerations \( a_A \), \( a_B \), and \( a_{\text{box}} \). **Graphical Analysis:** - Two circles with fixed centers \( O_2 \)
