Spiritual gifts are not innate, natural talents, like an ear for music or the ability to draw, but rather they are empowerments that the Holy Spirit gives to a believer to minister to the body in ways that were not possible by mere natural effort apart from the Holy Spirit.
In the design of a dam, the first step is the determination of various forces which acts on the structure and study their nature. Depending upon the situation, the dam is subjected to the following forces: 1. Water pressure. 2. Earthquake forces. 3. Silt pressure. 4. Wave pressure. 5. Ice pressure. 6.
Wind and wave forces are typically the controlling forces in the design of floating bridges. A major factor in wind and wave effects on floating bridges is called the fetch. The fetch is the unobstructed clear distance over the water that wind can travel to the bridge. The longer the fetch, the higher the wind and wave forces will be.
