Challenge Problems
Push your limits with challenges.
Question 1
An object with a volume of 3 m³ is submerged in water. Calculate the buoyant force acting on it, assuming the specific weight of water is 9.81 kN/m³.
💡 Hint: Use the specific weight of the fluid and the volume of the submerged object.
Question 2
A wedge-shaped object is submerged in mercury with a specific weight of 13.6 kN/m³. Its base measures 0.5 m², and the centroid is submerged 0.8 m deep. What is the resultant buoyant force?
💡 Hint: Calculate with the specific weight of mercury for accurate results.
