Compression steel

Given: The beam cross-section shown have the following cross-sectional properties: 

f'c = 4000 psi 

Find phi Mn. 

The image depicts a structural I-beam cross-section with detailed dimensions. It shows reinforcement placement and measurements.

### Description:
- **Overall Height:** 26 inches
- **Web Height:** 14 inches
- **Top Flange:**
  - Width: 16 inches
  - Reinforcement: 2 #8 rebars
  - Distance from the top edge to the first rebar: 3 inches
  - Distance from first to second rebar: 3 inches
- **Web Width:** 4 inches
- **Bottom Flange:**
  - Width: 16 inches
  - Reinforcement: 4 #9 rebars
  - Distance from the bottom edge to the first rebar: 3 inches
  - Distance from first to second rebar: 3 inches

This diagram is typically used in civil engineering and construction to provide precise reinforcement details for beam fabrication and placement.
