Challenge Problems
Push your limits with advanced challenges
You have a submerged rectangular surface with area A at a depth of h in water. Calculate the resultant force and location of the center of pressure if the second moment of inertia is known.
💡 Hint: Make sure to understand how to derive each component.
For a triangular surface submerged in water, with the top at depth h and a base width b, derive the equation for the center of pressure including the necessary integration steps.
💡 Hint: Consider how the triangle’s height affects the center of pressure calculation.
