Question
**Problem Statement:**
1. Given the figure below, plot the pore pressure, total stress, and effective stress at the top, bottom, and midpoint of each soil layer. Provide a plot with all numerical values of depth and stress in tabular form and on a depth vs. stress plot.

**Layer Details:**

- **Layer 1:** Sand
  - Depth Range: 0 ft to 30 ft
  - Moist Unit Weight (\(\gamma_{moist}\)): 122 pcf (pounds per cubic foot)
  - Saturated Unit Weight (\(\gamma_{sat}\)): 151 pcf
  - Water Table Level: 12 ft

- **Layer 2:** Clay
  - Depth Range: 30 ft to 70 ft
  - Saturated Unit Weight (\(\gamma_{sat}\)): 144 pcf

- **Layer 3:** Sand
  - Depth Range: 70 ft to 120 ft
  - Saturated Unit Weight (\(\gamma_{sat}\)): 128 pcf

**Depth Markers:**
- Ground surface - 0 ft
- Water Table - 12 ft
- First Layer Bottom - 30 ft
- Second Layer Bottom - 70 ft
- Third Layer Bottom - 120 ft

**Diagrams and Graphs:**
- A plot showing various soil layers with their respective unit weights and depth demarcations.
- A triangular symbol indicating the water table level at 12 ft within the first sand layer.
- Depth vs. Stress Plot with separate curves for pore pressure, total stress, and effective stress.

This educational exercise aims to extend understanding and application of geotechnical engineering principles by interpreting soil properties and generating stress distribution profiles throughout stratified soil layers.
