If a steel rectangular gate (see Figure 1) of 1.0m wide by 1.66 m high, is located in the wall of a reservoir. It is hinged at the top and acts as a relief valve such that when the water level reaches 1.35m above the top of the gate the gate starts to open allowing water to leave the reservoir. If the gate is inclined at 66º to the horizontal, and the density of steel is 7600 kg/m3, determine the thickness of the gate.
