An SP soil has a natural water content of 27.50% and total unit weight of 19.50 kN/m3 . The void ratios corresponding to the densest and loosest state of the soil are 0.51 and 0.87, respectively. Find the relative density and degree of saturation for this soil. Gs =270

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

The air in an automobile tire with a volume of 0.015 m3 is at 32°c and 140 kpa gage. determine the amount of air that must be added to raise the pressure to the recommended value of 206 kpa gage. assume the atmospheric pressure to be 128 kpa and the temperature and the volume to remain constant.[r-0.287 kj/kgk]
