Challenge Problems
Push your limits with advanced challenges
A curved arch of a bridge submerges 3 meters underwater with a horizontal cross-section of 8 square meters. Calculate the resultant force acting on the arch, assuming the fluid density is 1000 kg/m³.
💡 Hint: Use the density to determine pressure and multiply it by the area.
Analyze how the center of pressure would shift if the curved surface was tilted at a 30-degree angle compared to the horizontal. What would be the relationship observed?
💡 Hint: Consider how pressure changes with additional depth.
