Question

In the position shown, bar AB has an angular velocity of 4 rad/s clockwise. Determine the angular velocity of bars BD and DE. Solve using instantaneous velocity please. 

**Problem Statement:** In the position shown, bar \( AB \) has an angular velocity of \( 4 \, \text{rad/s} \) clockwise. Determine the angular velocity of bars \( BD \) and \( DE \). **Diagram Explanation:** The diagram illustrates a mechanical system of interconnected bars. Here's a detailed description: - **Bar \( AB \):** - Vertically positioned with a length of 250 mm. - The bar rotates clockwise about point \( A \) with an angular velocity of 4 rad/s. - **Bar \( BD \):** - Horizontally positioned with a length of 200 mm. - Connected to bar \( AB \) at point \( B \). - **Bar \( DE \):** - Angled downward with a length of 75 mm. - Connected to bar \( BD \) at point \( D \). - **Connections:** - Points \( A \), \( B \), \( D \), and \( E \) are pivots, allowing rotation. - The diagram shows distance measurements indicating the setup of the system: - 250 mm: vertical distance from \( A \) to \( B \). - 200 mm: horizontal distance from \( B \) to \( D \). - 75 mm: horizontal distance from \( D \) to \( E \). - 150 mm: vertical distance from \( E \) downward. **Objective:** - Calculate the angular velocities of bars \( BD \) and \( DE \) given the known angular velocity of bar \( AB \).
