Example 9.9. Separation in Time
Problem. Some buildings are supported by piles. The pile should have a
sharp tip to facilitate the driving process. However, the sharp piles have
reduced support capability. For better support capacity, the piles should
have blunt ends. However, it is more difficult to drive a blunt-tipped pile.
Contradiction. A pile should be sharp to facilitate the driving process but
blunt to provide better support of the foundation.
