Question
**Instruction for Structural Analysis:**

Determine the following properties for an L-shaped structural angle (specifically, L8x8x7/8) modeled as two rectangles forming the legs:

1. **Elastic Neutral Axis:**
   - Find the position where the stress transitions from compression to tension under bending.

2. **Elastic Section Modulus:**
   - Calculate the section modulus used to determine stress in elastic bending.

3. **Plastic Neutral Axis:**
   - Locate the axis where the area under compression equals the area under tension when the section yields.

4. **Plastic Section Modulus:**
   - Compute the modulus used for fully plastic bending.

**Task:**
Compare the calculated values to those given in the Manual to verify accuracy. 

By conducting these calculations, students will gain a deeper understanding of structural properties and validate theoretical knowledge with manual values.
