**Reinforced Concrete Beam Analysis**

A reinforced concrete beam with the provided cross-sectional dimension has a simple span of 26.5 feet. This beam supports uniformly distributed service loads of 4 kip/ft (live load) and 1.80 kip/ft (dead load), excluding the beam's own weight. The beam's reinforcement is depicted in the diagram.

**Objective:**  
Determine the maximum absolute values of the shear and bending moment for the beam, given:
- Concrete compressive strength, f'c = 3000 psi
- Steel yield strength, fy = 60,000 psi

**Diagram Explanation:**

- **Dimensions:** The cross-section of the beam shows a width of 16 inches.
- **Height Measurements:** The total height is 38 inches, with an upper portion of 35 inches where the reinforcing bars are positioned.
- **Reinforcement:** There are reinforcing bars located at the bottom section of the beam, spaced for optimal structural support.
  
The diagram provides essential data for calculating the maximum shear and bending moments necessary for structural analysis and design.
