Extracted text: A soil sample is subjected to an initial equal-all-around hydrostatic state of stress of 50 kPa. Sketch the stress paths for the loading conditions when: (a) oh remains constant and ov increases to 100 kPa; (b) ov is held constant while oh increases to 100 kPa; (c) Both oh and ov are increased to 100 kPa; (d) ov remains constant while oh decreases to 10 kPa; (e) ov is increased by 25 kPa at the same time that oh is decreased by 25 kPa.
