Question
**Problem Description:**

Two vertical forces, each of magnitude \( P = 26 \) kips, are applied to a beam of the cross-section shown. Determine the maximum tensile and compressive stresses in portion \( BC \) of the beam.

**Diagrams:**

1. **Cross-section of the Beam:**

   - The cross-section resembles an I-beam with the following dimensions:
     - Overall height of the section is 8 inches.
     - Thickness of the top and bottom flanges is 1 inch.
     - Width of the bottom flange is 4 inches.
     - Web thickness is 1 inch.
     - Depth of the web (distance between flanges) is 6 inches.

2. **Beam Diagram:**

   - A simply supported beam \( AD \) with \( AB = 20 \) in., \( BC = 60 \) in., and \( CD = 20 \) in.
   - Two forces \( P \) (26 kips each) are applied vertically downward on the beam at points \( B \) and \( C \).
   - Supports are located at points \( A \) and \( D \).

**Calculations Required:**

- Determine the maximum tensile stress (\(\text{ksi}\)) in portion \( BC \).
- Determine the maximum compressive stress (\(\text{ksi}\)) in portion \( BC \).
