For a concrete gravity dam with a triangular section, check the stability of a dam for rotation and overturning, translation and sliding and overstress and material failure for a normal loading condition. Design measure to make the dam safe against sliding, overturning (e. g., allocating drainage gallery, using grout curtain, pretension, and downstream supporting shoulder)

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
