When a dam is subjected to hydrostatic pressure from the water, the resultant force acts ____
11. When a dam is subjected to hydrostatic pressure from the water, the resultant force acts ____.
- Parallel to the dam's surface
- Perpendicular to the dam's surface
- Diagonally on the dam's surface
- At the base of the dam
Answer: B) Perpendicular to the dam's surface
Explanation:
The resultant force due to hydrostatic pressure on a dam acts perpendicular to the dam's surface. It is commonly known as the hydrostatic thrust.
