![**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 \( B \):
\[ F_B = \]
