**Problem: Calculating Force in a Rotating System** The crank \( OA \) rotates in the vertical plane with a constant clockwise angular velocity \( \omega_0 \) of 2.8 rad/s. For the position where \( OA \) is horizontal, calculate the force under the light roller \( B \) of the 18.1-kg slender bar \( AB \). **Diagram Explanation:** The diagram shows a mechanical system with the following components and dimensions: - A crank \( OA \) with a length of 0.51 meters. - A slender bar \( AB \), which is 1.30 meters long. - The bar \( AB \) is positioned vertically downward when the crank \( OA \) is horizontal, with a vertical distance from point \( O \) to point \( B \) measuring 1.02 meters. - The angular velocity \( \omega_0 \) is indicated at the pivot \( O \). **Solution:** To solve for the force \( F_B \) under the roller \( B \): \[ F_B = \] **Answer:** Enter the calculated force in Newtons (N) in the space provided.
