Question 1.
Define resultant force in the context of fluid mechanics.
Show hintHide hint
Think about how fluids exert force over areas.
Question 2.
What does gauge pressure indicate?
Show hintHide hint
It relates to height and density of fluid.
3Question 3.
What is the equation for the resultant force acting on a submerged surface?
- FR = P * A
- FR = ρgh * A
- FR = ∫P dA
Show hintHide hint
Remember the integration process!
4Question 4.
True or False: The center of pressure always coincides with the centroid of the area.
- True
- False
Show hintHide hint
Consider pressure changes with depth.
Question 5.
A rectangular gate is submerged under water with a width of 2 m and a height of 3 m. Calculate the resultant force acting on the gate.
Show hintHide hint
Consider the pressure at the centroid of the gate.
Question 6.
For a triangular surface submerged in fluid with base 4 m and height 3 m, calculate its center of pressure from the vertex.
Show hintHide hint
Use properties of centroids and the moment of inertia for the calculations.
