Document Summary
Unfilled height of the shear box after placing the top porous stone. Mass of the sand + pan (before use) Mass of the sand + pan (after use) The dry density may be calculated using the equation; Dry density (pd) = dry mass (m) / volume (v) Where mass is in grams, and volume is in g/cm3. The dry mass (m) is calculated below, subtracting the mass of the sand + pan (after use)" from the mass of the sand + pan (before use)"; = [( 632)/4](h) h = (height of the shear box) (thickness of the top porous stone) (unfilled height of the shear box after placing the top porous stone) h = 36. 15 6. 5 10. 98 h = 18. 67mm. Therefore the dry density (pd) can be calculated to be; The vertical load may be determined using the equation below; The vertical load is known to be 400n (refer to table 1).
