Question
**Problem 2:** A simply supported beam made of \( f'_c = 6000 \, \text{psi} \) concrete spans 80 ft between supports. The beam carries a dead load of 1.6 kip/ft and a live load of 2 kip/ft. 

a.) Using ACI code requirements, determine \( V_u \) at the critical location.  
b.) Check if the section meets ACI code requirements for \( V_{s,max} \).  
c.) At the critical section, find the required spacing (to the nearest inch) of no. 4 stirrups with a \( f_{yt} = 60,000 \, \text{psi} \).

### Diagram Explanation:

The diagram illustrates a cross-section of the beam. Key dimensions are marked:

- The total height of the section is 50.25 inches.
- The width of the central web portion is 6.5 inches.
- The shaped flanges and reinforcement details are also visible, showing positions and distributions of potential reinforcement (indicated by circles).

This diagram helps visualize the critical dimensions needed for the analysis and design calculations based on the problem statement.
