**Problem 1:**  
**Problem 14.5 Textbook (modified)**  
The loads on a beam and its cross section are shown in Figure P14.4; f'c = 4000 psi, fy = 60,000 psi. Is this beam adequate?

**Figure P14.4:**

- **Diagram Description:**
    - The figure includes two diagrams. The first is a layout of a simply supported beam with a total span of 20 feet, split into two equal segments of 10 feet, with a central load of 10 k.
    - The beam is subjected to a uniformly distributed load:
        - Dead load (Dꞌ) excluding the beam's weight: 0.5 k/ft.
        - Live load (Lꞌ) for service loads: 0.75 k/ft.

- **Cross Section Diagram:**
    - The second diagram shows the cross-sectional details of the beam.
        - The width of the beam: 12 inches.
        - The total depth of the beam: 17 inches.
        - There are 4 #8 rebar for reinforcement located at specific positions on the cross-section.

This setup aims to determine whether the given beam can withstand the specified loads considering the material properties (compressive strength of concrete, f'c = 4000 psi, and the yield strength of reinforcement steel, fy = 60,000 psi).
