The centre of pressure is_________________?
Correct answer: C. A point on the line of action of the resultant force
- A. Always below the centroid of the area
- B. Always above the centroid of the area
- C. A point on the line of action of the resultant force
- D. At the centroid of the submerged area
Explanation
The centre of pressure is the point through which the resultant hydrostatic force acts, so it lies on the resultant force's line of action. It is not always above or below the centroid because its position depends on the submerged geometry and pressure distribution.
