Question 1
What is the formula to calculate hydrostatic pressure as a function of depth?
- p = ρgh
- p = hg/ρ
- p = A/F
💡 Hint: Think about how pressure changes as you go deeper underwater.
Question 2
Is the resultant force always directed vertically upwards?
- True
- False
💡 Hint: Consider how pressure acts at a point.

Challenge Problems
Push your limits with challenges.
Question 1
A trapezoidal plate is submerged at an angle in water. The top base is 1m long, the bottom base is 2m long with a height of 1m. Calculate the total resultant force acting on one face if the water depth is 3 meters.
💡 Hint: Break down into differential elements and integrate the pressure.
Question 2
A submerged object has its centroid located 2 meters below the water surface. If it displaces 1500 kg of water, calculate the buoyant force acting on the object.
💡 Hint: Remember that density of water is 1000 kg/m³.
