Consider the following statements about the stability criteria of a gravity dam: Statement I: If the force of friction is more than the force due to water pressure, the dam is safe against sliding. Statement II: If the resultant of the weight of the dam and the horizontal force due to water pressure lies outside the base of the dam, but within h (where h is the height of the dam) from the face of the dam, the dam is safe against overturning. Statement III: To avoid tension at the base of the dam, the maximum value of eccentricity is b/6 on either side of the geometrical axis of the base section, where b is the base width of the dam. Which of the given statements is/are correct?
