If A is the area of the foundation of a retaining wall carrying a load W and retaining earth of weight 'w' per unit volume, the minimum depth (h) of the foundation from the free surface of the earth, is$? |
| A. | h = (W/Aw) [(1 - sin φ)/(1 + sin φ)] |
| B. | h = (W/Aw) [(1 + sin φ)/(1 + sin φ)] |
| C. | h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]² |
| D. | h = ‚à ö(W/Aw) [(1 - sin œÜ)/(1 + sin œÜ)]¬≤ |
| Answer» D. h = ‚Äö√ √∂(W/Aw) [(1 - sin ≈ì√ú)/(1 + sin ≈ì√ú)]¬¨‚⧠| |
