What is a pound of thrust? Thrust is measured in “pounds of thrust” in the U.S. and in newtons in the metric system. 4.45 newtons of thrust equals 1 pound of thrust. A pound of thrust is how much thrust it would take to keep a one-pound object unmoving against the force of gravity on […]
What is the difference between a random error and a systematic error?
What is the difference between a random error and a systematic error? Random errors show up as different results for ostensibly the same repeated measurement. They can be estimated by comparing multiple measurements, and reduced by averaging multiple measurements. Systematic error is predictable and typically constant or proportional to the true value. What is an […]
What is the Maxwell model of viscoelasticity?
What is the Maxwell model of viscoelasticity? The Maxwell model predicts that stress decays exponentially with time, which is accurate for most polymers. One limitation of this model is that it does not predict creep accurately. The Maxwell model for creep or constant-stress conditions postulates that strain will increase linearly with time. Why are polymers […]
Is rate of decay constant?
Is rate of decay constant? The rate of decay remains constant throughout the decay process. There are three ways to show the exponential nature of half-life. What is a rate of decay? The rate of decay is often referred to as the activity of the isotope and is often measured in Curies (Ci), one curie […]
What was the first PC based operating system called quizlet?
What was the first PC based operating system called quizlet? Terms in this set (25) Microsoft Windows was the first operating system with a user interface based on windows and icons. Does M2M communication allows computers to monitor equipment on assembly lines? Answer Expert Verified. Type of communication where a company’s computers can monitor assembly […]
What is a boundary layer in fluid mechanics?
What is the mechanism of grain refinement strengthening?
What is the mechanism of grain refinement strengthening? It is based on the observation that grain boundaries are insurmountable borders for dislocations and that the number of dislocations within a grain have an effect on how stress builds up in the adjacent grain, which will eventually activate dislocation sources and thus enabling deformation in the […]
How is the Apriori property used in the algorithm?
How is the Apriori property used in the algorithm? Apriori is an algorithm for frequent item set mining and association rule learning over relational databases. The frequent item sets determined by Apriori can be used to determine association rules which highlight general trends in the database: this has applications in domains such as market basket […]
What are the contributing factors to gender based violence?
What are the contributing factors to gender based violence? Various other factors, such as poverty, lack of education and livelihood opportunities, and impunity for crime and abuse, also tend to contribute to and reinforce a culture of violence and discrimination based on gender. What are factors that contribute to violence? Individual Risk Factors History of […]
How are metallic glasses formed?
How are metallic glasses formed? Explanation: Quenching means rapid cooling. Actually atoms of any material move freely in a liquid state. Atoms can be arranged regularly when a liquid is cooled slowly. Instead, when a liquid is quenched, there will be an irregular pattern, which results in the formation of metallic glasses. What are metallic […]
