![### Educational Content on Beam Design
**Problem Statement:**
For a non-rectangular beam:
- Concrete is rated at \( f'_c = 6 \) ksi.
- Steel is rated at \( f_y = 60 \) ksi.
- Effective depth \( d = 12.5 \) inches.
**Tasks:**
(a) **Determine the area of the steel** for a balanced system for the shown area of concrete.
(b) **Determine the moment capacity** of the beam, \( M_n \).
(c) **Determine the neutral axis** \( c \).
**Diagram Explanation:**
The diagram illustrates the cross-section of a non-rectangular beam, providing dimensions and notation for calculations:
- The top flange and the dimensions contributing to the beam’s shape are labeled.
- The cross-section helps in identifying the effective depth \( d = 12.5 \) inches from the top of the beam to the centroid of the tensile reinforcement.
- The diagram also shows locations and notation for calculating the centroid, reinforcing bars, and areas specific to the concrete and steel components.
Use this information to perform structural calculations necessary for determining the balanced system's reinforcement area, moment capacity, and the neutral axis position.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F535a6610-5408-42b9-810f-cca1f66cb656%2F0f82fb5b-c9fc-425f-b34f-b8f13ca13aa0%2Fzeymn7n_processed.jpeg&w=3840&q=75)
