1B. A 3-ft wide gate (AB) is designed to hold back a 6-ft deep reservior. Assuming the water has a specific weight y = 62.5 lbs/ft, determine the magnitude of the equivalent hydrostatic force of the water acting on the gate (Fea). If the gate was cemented into the ground creating a fixed support at the ground (A), determine the magnitude of the reaction moment at the ground (MA) that would be required to hold the gate in static equilibrium.
