A hemispherical viewing port in a museum aquarium (Figure P2.6.3) has a 1-ft radius. The top of the viewing port is 3 ft below the water surface (h). Determine the magnitude of the horizontal component of the hydrostatic force acting on the viewing port. Also, determine the resultant hydrostatic force and its direction if the vertical force component equals 261 lb acting upwards. Note that the resultant force will pass through the center of the sphere since all pressures are normal to the surface and will pass through this point. h
