1. Given a concentrated load of 200,000 Ibs, find the vertical stress (p) at a depth of 15 ft and 10 ft off-center. Use the Boussinesq equation. 2. Given a rectangular area with dimensions of 2 m by 3 m and a load of 195 kN/m2; find the vertical stress (p) in kN/m2 using the Approximation Method for a depth of 1m, 3m, and 5m. With increasing depth how does the pressure change? 3. Given a circular structure with a diameter of 3 m and a load of 250 kN/m2, find the vertical stress (p) using the circular method based on elastic theory at a depth of 3 m and 1.5 m off-center. Given a soil unit weight (g) of 16.38 kN/m3, find the overburden pressure (Po) at a depth of 3 m. Find the total pressure (p+po).
