What are the equivalence classes of the equivalence relations in Exercise 3? What are the equivalence classes of the equivalence relations in Exercise 3? A binary relation defined on a set S is said to be equivalence relation if it is reflexive, symmetric and transitive. An equivalence relation defined on a set S, partition the […]
What are the surface defects?
What are the surface defects? Surface defects are the boundaries, or planes, that separate a material into regions, each region having the same crystal structure but different orientations. What are the types of line defect? Point defects (vacancies, interstitial defects, substitution defects) Line defect (screw dislocation, edge dislocation) surface defects (material surface, grain boundaries) Substitutional […]

What happens during tempering of steel?
What happens during tempering of steel? Tempering, in metallurgy, process of improving the characteristics of a metal, especially steel, by heating it to a high temperature, though below the melting point, then cooling it, usually in air. The process has the effect of toughening by lessening brittleness and reducing internal stresses. What does tempering do […]
Where does the air in a pneumatic system come from?
Where does the air in a pneumatic system come from? Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor. The compressor sucks in air from the atmosphere and stores it in a high pressure tank called a receiver. This compressed air is […]
What is not true about machine learning?
What is not true about machine learning? Machine learning is artificial intelligence. Yet artificial intelligence is not machine learning. This is because machine learning is a subset of artificial intelligence. In addition to machine learning, artificial intelligence comprises such fields as computer vision, robotics, and expert systems. Which of the following is true about machine […]
What is a thermally activated process?
What is a thermally activated process? A Thermally Activated Process is one in which the system must overcome an energy barrier in order for the process to go forward. The rate of these types of processes rises exponentially with temperature. What is recrystallization used for? Recrystallization is the most important method of purifying nonvolatile organic […]
What is the thermal efficiency of the cycle?
What is the thermal efficiency of the cycle? The thermal efficiency of modern steam turbine plants with reheat cycles can reach 47%, and in combined cycle plants, in which a steam turbine is powered by exhaust heat from a gas turbine, it can approach 60%. Which cycle has the highest thermal efficiency between two temperatures? […]
Can you use microwave with generator?
Can you use microwave with generator? When experiencing a power outage, you can use a gas-powered generator to run various electrical appliances, including a microwave oven. Before attempting to connect the microwave to your generator, you must make sure to size the generator properly, otherwise the microwave will not operate at its full capacity. How […]
