What is excess notation? Excess notation is a form of representing signed numeric values. In excess notation, the first bit of the representation is fixed for the sign, where 1 represents positive numbers and 0 represents negative numbers. Typically, computers use 64 or 128 bit format, but here only 4-bit format is being used. What […]
What is electronegativity trend?
What is electronegativity trend? The electronegativity trend refers to a trend that can be seen across the periodic table. This trend is seen as you move across the periodic table from left to right: the electronegativity increases while it decreases as you move down a group of elements. Which best describes the trends in electronegativity […]
How do you describe a function in algebra?
How would you use the WBS in risk identification assessment?
How would you use the WBS in risk identification assessment? By looking at the WBS, the risk management team can go through each task in the WBS and identify specific events that can lead to risks relating to each task. Using the WBS will help ensure that the team comprehensively covers as many specific areas […]
How do I choose shaft diameter?
How do I choose shaft diameter? Resistance to torsional stress is directly proportional to shaft size: the larger the diameter, the greater the resistance to twisting. A rule of thumb with this method is that the shaft must be large enough that it will not deflect more than 1 degree in a length of 20 […]
What is stationary refrigeration?
What is stationary refrigeration? Refrigerant emitted during the normal operation of air-conditioning and refrigeration equipment (as opposed to during the maintenance, servicing, repair, or disposal of this equipment), such as from mechanical purging and leaks. … Is venting R134a illegal? R134a is not an ozone-destroying agent, but it is a greenhouse gas, and is illegal […]
What happens at boundaries where plates collide or separate?
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 […]
