Question
**Rectangular Beam Design**

1. **Material Properties**:
   - Yield strength of steel (\(f_y\)): 60,000 psi
   - Compressive strength of concrete (\(f'_c\)): 4,000 psi

2. **Reinforcement Ratio**:
   - ρ (reinforcement ratio) ≈ 0.2*\(f'_c\)/\(f_y\)

3. **Beam Specifications**:
   - Simple span length: 25 ft.
   - Dead load (including beam's own weight): 1 k/ft
   - Live load: 3 k/ft

## Task:
Design a rectangular beam to meet the above requirements. The beam should be capable of supporting the combined dead and live loads over the specified simple span.
