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 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 […]
What are the four 4 stages of supply chains?
What are the four 4 stages of supply chains? There are four customary stages in a product’s life cycle: the introductory phase, the growth phase, the maturity phase and the decline phase. Each phase is markedly different and often requires different value chains. Supply managers need to craft supply strategies that reflect the unique needs […]
How is the heat added in the Otto cycle?
How is the heat added in the Otto cycle? Through the combustion of fuel, heat is added in a constant volume (isochoric process) process, followed by an adiabatic expansion process power (C) stroke. The cycle is closed by the exhaust (D) stroke, characterized by isochoric cooling and isobaric compression processes. In which of the following […]
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 […]
How did technology affect aviation?
How did technology affect aviation? It’s already having an impact on safety and maintenance, allowing airlines to keep their planes in the air longer, with less time spent on the ground. Another important technology that will impact airlines is cloud computing. In a cloud setup, IT vendors can provide resources to an airline remotely as […]
What is frequency response of LTI system?
What is frequency response of LTI system? Frequency response is the quantitative measure of the output spectrum of a system or device in response to a stimulus, and is used to characterize the dynamics of the system. It is a measure of magnitude and phase of the output as a function of frequency, in comparison […]

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 […]
