Question 1696 Deck Safety

The correct answer is A) approximately one-third of the way up the bulkhead. The center of pressure of the shores on a bulkhead subjected to solid flooding should be located approximately one-third of the way up the bulkhead. This is based on the principle that the center of pressure of a liquid acting on a vertical surface is located at one-third the depth of the liquid. Since solid flooding behaves similarly to a liquid, the same principle applies. The other options are incorrect because: B) Evenly distributing the shores over the surface of the bulkhead would not account for the increased pressure at the bottom; C) Placing the shores at the bottom would not provide adequate support against the higher pressures higher up the bulkhead; and D) Placing the shores halfway up the bulkhead would not be the optimal location for the center of pressure.
