Homework Answers
Neutral stress is the stress exerted on its surroundings by water held in pore spaces in rock or soil. The stress is positive when a soil is fully saturated, and is then proportional to the height of the water measured in an open tube (a piezometer) above the point of interest.Hence neutral stress results from WATER TABLE so option 1. is correct.
