Correct answer: A. At the toe
- A. At the toe
- B. At the heel
- C. Within the middle third of base
- D. At centre of base

When the reservoir is full, hydrostatic pressure shifts the resultant toward the downstream side, increasing the compressive stress at the toe. The heel may experience reduced compression or even tension under some loading conditions.
