4 cards from this section. Quick, good the night before a test.
What is the formula for calculating the resultant force on a horizontal plane area submerged in a fluid?
Consider how pressure is affected by depth.
Where does the resultant force act on a plane surface?
Think about where pressure is best represented.
What is the resultant force on a submerged surface directly proportional to?
Recall how pressure is affected by both these factors.
True or False: The center of pressure is always at the centroid.
Consider how pressure acts differently at various points.
A triangular plate with a base of 2 m and height of 3 m is submerged at an angle. Calculate the resultant force acting on it and determine the location of the center of pressure.
Approach by breaking down the height increments.
You have a circular gate submerged in water at a depth of 5 m. Calculate the total force acting on the gate as well as the center of pressure. Dimensions of the gate are radius 1 m.
Think about how the circle simplifies the integration for circular sections.
