Shear Strength Tests - Lab Report Example Top and bottom was joined using shear screws half of the shear box and solid 3mm plate was placed at the bottom of the shear box then the height d1 from the top of the plate to the bottom shear box was measured. A container containing sand weighing 0.1g was poured evenly into the Shear box from 5cm height 10mm from the top. The scraper was used to level the sand, and the weight of the sand sample within the shear box was measured. The thickness of the second plate 3mm plate, tp, and its weight was measured and recorded. Vernier ruler was used to measuring the distance from the top of the plate to top of the box at all 4 corners to 0.1mm then the average was recorded as d2. Sample volume, weight, density, and porosity was calculated. The computation of the porosity was based on sands grains possessing relative density Gs of 2.65.1.2  Loading the Sample Vertically  The Piston was weighed and gently placed on the top plate, and the vertical loading hanger was aligned onto the piston . The Vertical spindle was gently threaded until in contact with the piston. The locking nut was adjusted to keep the spindle in place and the load was placed on the lower hanger through turning handle. The lower hanger lever gave a 10 times multiplication of the load at the loading point, and the weight were recorded.1.3. Readying Sample for Shearing  The screws were joining the top and the bottom half of the box was removed, and all the dials were set to zero to ensure they fully engage and the coefficients value for each division was recorded.
