Shear Strength Tests - Lab Report ExampleTop and bottomland 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 spinning top 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 system of saddles 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 surmount 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 porousness was calculated. The computation of the porosity was based on sands grains possessing relative density Gs of 2.65.1.2Loading the Sample VerticallyThe Piston was weighed and gently placed on the top plat e, and the vertical lode 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 agitate 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 ShearingThe 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 cheer for each division was recorded.
