A submerged triangular surface has a base of 4m and height of 3m. Calculate the resultant force if submerged to a depth of 6m in water (γ = 9.81 kN/m³).
💡 Hint: Break it down into steps: calculate area first, then centroid, and finally resultant force using the formula.
You have a circular gate of diameter 2m submerged in water up to a depth of 4m. Find the position of the center of pressure.
💡 Hint: Remember to convert the diameter to radius and apply the correct formula for circular areas.
