6.2. Triangle Properties

Try these first

1. 1.

   What is the formula for calculating pressure at a depth 'h' in a fluid?

   Hint

   Think about the factors that contribute to pressure in a fluid.

2. 2.

   Define what is meant by 'buoyant force'.

   Hint

   Consider what pushes upwards against the weight of the submerged object.

3. 3.

   What happens to pressure as you dive deeper into a fluid?

   • It increases
   • It decreases
   • It remains the same

   Hint

   Consider what is pushing down from above.

4. 4.

   True or False: The center of pressure always lies below the centroid.

   • True
   • False

   Hint

   Think about how depth influences pressure distribution.

5. 5.

   A rectangular gate with a height of 4m is submerged in water. What is the resultant force acting on the gate?

   Hint

   Split the calculation into different pressure components.

6. 6.

   Determine the center of pressure for an inclined triangle with a base of 3m and height of 2m submerged.

   Hint

   Find the centroid first. What would the dimensions be in relation to each axis?
