Determine the magnitude, direction, and line of action of the vertical and horizontal components of hydrostatic force acting on a surface.
For the curved surface AB:
a. find out the magnitude, direction, and line of action of the vertical component of hydrostatic force acting on the surface. Here l = 1 m.
b. conclude the magnitude, direction, and line of action of the horizontal component of hydrostatic force acting on the surface.
