3.1 A truck loaded with 2 m³ dry sand appears to weigh "3 tons" more than the weight of the empty truck. What is the meaning of the term *3 tons", and what is the volumetric weight of the sand? Problem 3.2 If it is known that the density of the sand particles in the material of the previous problem is 2600 kg/m³, then what is the porosity n? And the void ratio e? Problem 3.3 It would be possible to fill the pores of the dry sand of the previous problems with water. What is the volume of the water that the sand could contain, and then what is the volumetric weight of the saturated sand? Problem 3.4 The soil in a polder consists of a clay layer of 5 meter thickness, with a porosity of 50 %, on top of a deep layer of stiff sand. The water level in the clay is lowered by 1.5 meter. Experience indicates that then the porosity of the clay is reduced to 40 %. What is the subsidence of the soil? 3.1 A truck loaded with 2 m³ dry sand appears to weigh "3 tons" more than the weight of the empty truck.
