Select all true statements. ANFO explosive is often preferred because using bulk explosives is cheaper, less labor intensive during loading and they fill the entire blast hole diameter. Emulsion explosives should not be used in strong and massive rocks where a high detonation pressure and high detonation velocity is required to break the rock. During rock fragmentation by blasting, the reflection of the compression wave at the free face into tension and shear waves contributes to additional cracking between the free face and the blast hole. When metals or other reactive elements are present in the composition of an explosive, less oxygen is required for a an oxygen-balanced reaction.
For an application of high strength components including gears cams and rollers the desired properties in a plastic would be high tensile and impact strength, stability at high temperature, and machine ability. Potential materials which are suitable for these applications are nylon phenolics, TFE filled acetals, PET, and poly carbonate. True or false.
Task 1 You have been moved into the laboratory for the fluid testing for hydraulic devices and a considerable amount of research has been carried out in an attempt to understand the exact nature of the temperature variation of viscosity. Inspect the table given below and note the relative values of viscosity for each Newtonian fluid at a given temperature. Compare the results of a viscosity test and comment on why the viscosity of ethanol and water is considerably lower than motor oil and explain any discrepancies. Temperature [°C] Water (μ) Ethanol (μ) Motor oil (SAE 15W-40) (μ) [mPa s]/ cP [mPa s]/ cP [mPa s]/ cP 10 1.30600 1.4475 582.95 20 1.00160 1.1841 287.23 30 0.79722 0.9764 155.31 40 0.65272 0.8151 91.057 50 0.54650 0.694 57.172 60 0.46602 0.6034 38.071 70 0.40353 0.5231 26.576 80 0.35404 0.01043 19.358 90 0.31417 0.01074 14.588 100 0.28158 0.1104 11.316 To complete this task, it is required to evaluate the effects of shear force on three Newtonian and three non-Newtonian…
