2. Sand at a given relative density has a friction angle of approximately 33° (relatively low stress). When the sample is unsaturated at a given value of saturation (not given to you), the specimen has a negative pore pressure of 5 kPa. How tall a sandcastle "vertical" wall can you construct? What would happen to your sandcastle if the level of saturation suddenly increased? (Assume a total unit weight of 18 kN/m³)
