A tank is divided into two sections by a 1 × 1-m square gate that is hinged at A. A couple of magnitude 490 N · m is required for the gate to rotate. If one side of the tank is filled with water at the rate of 0.1 m3 / min and the other side is filled simultaneously with methyl alcohol (density (ma = 789 kg/m3) at the rate of 0.2 m3/min, determine at what time and in which direction the gate will rotate.
