What is the purpose of JIT? Just-in-time (JIT) inventory is a stratagem that manufacturers utilize to increase efficiency and decrease waste by receiving goods only as they are needed in the manufacturing process, thereby reducing the cost of inventory. Importantly, manufacturers must forecast their requirements accurately. What JIT means? Just-in-time also known as JIT is […]

What is an API and why we use APIs in Web applications? API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you’re using […]

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? 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? 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? 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 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? 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 […]

How are the average friction and heat transfer coefficients determined in flow over a flat plate? The average friction and heat transfer coefficients in flow over a flat plate are determined by integrating the local friction and heat transfer coefficients over the entire plate, and then dividing them by the length of the plate. What […]

How is Otto cycle efficiency calculated? When we rewrite the expression for thermal efficiency using the compression ratio, we conclude the air-standard Otto cycle thermal efficiency is a function of compression ratio and κ = cp/cv. What four processes make up the ideal Otto cycle? The four-stroke Otto cycle is made up of the following […]
