*c*′ = 31.1 kN/m^{2}, and *γ* = 18.0 kN/m^{3}

b. *n*′ = 1,
*c*′ = 24 kN/m^{2}, and *γ* = 18.0 kN/m^{3}

c. *n*′ = 2.5,
*c*′ = 25 kN/m^{2}, and *γ* = 17 kN/m^{3}

d. *n*′ = 1.5,
*c*′ = 18 kN/m^{2}, and *γ* = 16.5 kN/m^{3}

**FIG. 13.38**

(a)

To determine

Find the critical height of the slope.

Explanation

**Given information:**

**Calculation:**

Calculate slope angle

Substitute 2 for

Find the Taylor’s stability number (*m*).

Refer Figure 13.17, “Taylor’s stability number” in the textbook

(b)

To determine

Find the critical height of the slope.

(c)

To determine

Find the critical height of the slope.

(d)

To determine

Find the critical height of the slope.
