Challenge Problems
Push your limits with challenges.
Question 1
A square gate measuring 1.5 m x 1.5 m is fully submerged. If the water density is 1000 kg/m³ and the gravitational force is 9.81 m/s², calculate the force acting on the gate and the moment about the hinge.
💡 Hint: Calculate pressure at the midpoint and remember to consider the right distance for the moment.
Question 2
Given a rectangular gate submerged 2 meters in water, how do you derive the necessary vertical force required for maintaining stability around the hinge?
💡 Hint: Set the counteracting moments around the hinge to zero.
