Triaxial undrained test
The results obtained from the Mohr plot indicate that the soil has a high cohesion (306.68 kN/m2) but a small angle of friction (15. In turn this can be used to surmise that the soil sample under investigation has relatively good shearing properties although it is prone to failure if the angle of repose is increased by a large amount. The other thing to take note of is whether the soil sample under investigation has been packed properly before investigation or not. It could be that the small

The most advisable temperature range for cylinders are between 400- 570°F. Normally the temperature should be 25-50°F above the normal temperature when molding polypropylene. However it should not be molded above 570°F so the normal range for molding would be kept anywhere between 400-525°F. The cylinder temperature is best kept with the hopper or feed section lower than the nozzle at 30-50°F. Using a bell shaped temperature profile is recommended when greater mixing is expected and the
