Which failure occurs when the minimum stress exceeds the allowable compressive stress of the dam material?

Which failure occurs when the minimum stress exceeds the allowable compressive stress of the dam material? Correct Answer Crushing

The compressive stress produced if exceeds the allowable stresses then the dam material may get crushed, a dam may fail by the failure of its own material. The allowable compressive stress of concrete is generally taken as 3000 KN/m2.

Which of the following statements are true with regard to energy dissipation below a dam? (i) If the upper conjugate depth of a hydraulic jump is below the tailwater, little energy will be dissipated (ii) An upturned bucket will protect the dam from scour by moving material toward the dam. (iii) A secondary dam may increase tailwater height, thereby causing a hydraulic jump to form at the toe of the main dam. (v) A slopping apron above streambed level may be used to control the hydraulic jump so that it occurs on the apron. 
Each material circumstance appearing in evidence against the accused must be put to the accused specifically, distinctly and separately. In this context, the propositions are
1. Failure to put the material evidence to the accused always vitiates the trial
2. Failure to put the material evidence amounts to a serious irregularity which can not be cured and vitiates the trial, if it has prejudiced the accused.
3. Failure to put the material evidence is not considered to services & is curable if infact no failure of justice has occasioned to the accused.
