A. What is the depth where we are going to find the ocean crust that is 50 million years old. Consider that the depth of the mid-ocean ridge is 1000 m. B. The spreading of the middle ocean ridge is 5 cm/yr. B.In what distance from the middle ocean ridge, you are going to find the position of the depth that you calculate in question A. C Considering now that the velocity of the spreading center is double the previous from question B, in what distance you will find the same depth as in question A and what do you believe will be the effect in the sea level considering that the water volume in ou

Refer to Figure 8.13. The magnitude of the line load q is 45 kN/m. Calculate and plot the variation of the vertical stress increase, between the limits of x = 10 m and x = +10 m, given z = 4 m. FIG. 8.13 Line load over the surface of a semiinfinite soil mass

Refer to Figure 8.24. Determine the vertical stress increase, , at point A with the following values: q1 = 100 kN/m x1 = 3 m z = 2 m q2 = 200 kN/m x2 = 2 m FIG. 8.24 Stress at a point due to two line loads

Refer to Figure P3.3. Use Eqs. (3.10) and (3.11) to determine the variation of OCR and preconsolidation pressure c. FIGURE P3.3
