   For no tension to develop in the gravity dam the eccentricity 'e' of the resultant force should be

   1. Less than b/3
   2. Less than b/6
   3. Less than b/4
   4. Less than b/12
   Show answer

   Answer: (2) Less than b/6

   Base stress = (ΣV/b)(1 ± 6e/b), so the heel stays in compression only if e ≤ b/6, i.e. the resultant lies within the middle third of the base.
