Since the vertical component of force = weight of the fluid contained by the curved surface . So it will act at the centre of gravity of the corresponding weight. For eg. For a quarter circle it will act at a distance of 4R/3π from straight edge.ual8658 said:I get how to find vertical and horizontal forces on a submerged surface (vertical = weight of fluid and horizontal = force on vertical projection). I also get how to find the point of application for the horizontal force using a moment balance. But how do you determine the point of application for the vertical force on the surface if that surface is something like a flat incline or a quarter circle?

Hope it is clear now.
Precisely.ual8658 said:Oh so just the centroid of an area basically? But only take the x-component of the centroid if its a vertical force.
Fluid mechanics is a branch of physics that deals with the behavior of fluids (liquids, gases, and plasmas) at rest and in motion. It involves the study of properties such as flow rate, viscosity, pressure, and density of fluids, and their effects on objects in their path.
The force point of application is the point at which a force is applied to an object. In fluid mechanics, it refers to the specific location where a force is exerted on a fluid, such as a solid object moving through the fluid or a fluid being pushed or pulled by an external force.
The force point of application can be found by considering the direction and magnitude of the applied force and the properties of the fluid, such as its density and viscosity. It can also be determined through experiments and calculations using mathematical equations and principles of fluid mechanics.
Knowing the force point of application is important in understanding the behavior of fluids and their interactions with objects in their path. It can also help in the design and optimization of various systems that involve fluid flow, such as airplanes, pumps, and pipelines.
Some common applications of finding the force point of application in fluid mechanics include designing efficient aerodynamic shapes for vehicles, optimizing hydraulic systems, and calculating the lift and drag forces on objects in a fluid flow. It is also important in studying the effects of fluid flow on marine structures, such as ships and offshore platforms.
