Problem Statement: A dam of 200 m height has created a water reservoir in the flow path of a river. The dam is provided with a vertical lift gate of 10 m x 10 m size and 50 cm thickness to control the discharge of water from the reservoir. The bottom edge of the gate is located at a distance of 20 m from the base of the dam while it is in a fully closed position. The gate is equipped with four rollers at its corners which slide over a guideway and facilitate the upward and downward motion of the gate. The gate, rollers, and guideway are made up of stainless steel. A rope and pulley arrangement is coupled to a motor to facilitate the opening and closing of the gate. Determine the required torque rating of the motor.
