Challenge Problems
Push your limits with challenges.
Question 1
A cube of side 30 cm is fully submerged in water. Calculate the buoyant force and discuss its impact if the cube has a mass of 20 kg.
💡 Hint: Remember that buoyant force equals weight of fluid displaced!
Question 2
Design a rectangular gate (1.5m x 2m) under a water tank and calculate the force acting on it at a depth of 1m. Discuss how the pressure distribution affects the required force.
💡 Hint: Don't forget to consider the force's line of action for equilibrium analysis!
