**Problem Statement**Consider the beam in (Figure 1).Determine the magnitude of \( F \) so that the resultant couple moment is 450 lb·ft, counterclockwise.Express your answer in pounds to three significant figures.\[ F = \quad \text{lb} \]**Diagram Explanation**The diagram shows a horizontal beam with a series of forces acting on it and their respective distances marked. Key points in the diagram include:1. **Beam and Forces**: - The beam is shown horizontally. - Two forces of 200 lb each are acting perpendicular to the beam. One force is located 2 feet from the left end, directed upwards. The other is located 1.5 feet from the right end, directed downwards.2. **Force \( F \)**: - Two forces, each labeled \( F \), are acting at an angle of 30 degrees to the right end of the beam. - The point of application of \( F \) is 1.25 feet from the right end of the beam.**Instructions for Students**1. **Goal**: Calculate the magnitude of force \( F \) such that the resultant couple moment about the beam is 450 lb·ft acting counterclockwise.2. **Precision**: Ensure your answer is rounded to three significant figures and expressed in pounds (lb).3. **Submission**: Provide your calculated value in the text box and submit for evaluation. **Provide Feedback** to your solutions by using the provided link.
