Question

For problem 1, the top 2 inches of the beam is made of concrete with a compressive strenght of 8000 psi instead of 5000 psi. The rest of the beam has concrete with compressive strenght of 5000 psi.

**Title: Calculating the Nominal Moment Capacity of Beams**

**Instruction:**
Compute the nominal moment capacity for the following beams.

**Beam Details:**

- **Diagram:**
  - A rectangular beam with dimensions: 15 inches wide and 24 inches high.
  - The bottom section includes reinforcement with eight #8 bars.

- **Reinforcement Details:**
  - \( A_s \) = 8 - #8 bars
    - Area = 6.4 in²

- **Concrete Compressive Strength:**
  - \( f'_c \) = 5000 psi

- **Yield Strength of Steel:**
  - \( f_y \) = 60,000 psi

This setup is used to determine the beam's capacity to resist bending moments under specific material properties and reinforcement.
