What happens at boundaries where plates collide or separate? If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common. Which plate boundary […]
Why do brittle materials have high compressive strength?
Why do brittle materials have high compressive strength? • Brittle materials are well known to be much stronger in compression than in tension. This is because under a compressive load a transverse crack will tend to close up and so could not propagate. Is ductile or brittle stronger? In general, soft tough metals will be […]
What are the equivalence classes of the equivalence relations in Exercise 3?
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 […]
Whats another name for a service overcurrent device?
Whats another name for a service overcurrent device? Overcurrent protective devices, or OCPDs, are typically used in main service disconnects, and in the feeders and branch circuits of electrical systems for residential, commercial, institutional, and industrial premises (Figure 5.3). Figure 5.3. Overcurrent protection devices include circuit breakers and fuses. What is a branch circuit overcurrent […]

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? […]
