1. For the shear strength versus normal stress graph in Figure 1 and the shear strength relationship, i.e., \( S = c + \sigma \tan \phi \); identify the shear strength parameters in the equation and find their values from Figure 1.

    a) Symbol: ____ Name: ___________________________ Value: ______ Units: ______

    b) Symbol: ____ Name: ___________________________ Value: ______ Units: ______

![Graph](#)

**Figure 1.** Shear strength versus normal stress from a direct shear test.

- **X-axis (Horizontal):** Normal Stress, \(\sigma\) (psf)
- **Y-axis (Vertical):** Shear Strength, \(S\) (psf)
- The graph shows a linear relationship with data points marked and a trend line fitted through them.

2. Calculate the shear strength for an effective normal stress of 4500 psf.
