How does a CNC machine work? The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions. On the industrial machines there is usually a sophisticated feedback system that constantly monitors and adjusts the cutter’s speed and position. What is CNC machine […]
What is the gain of non-inverting amplifier?
What is the gain of non-inverting amplifier? A non-inverting amplifier uses a voltage-divider-bias negative feedback connection. The voltage gain is always greater than one. The voltage gain is positive, indicating that for AC input, the output is in-phase with the input signal and for dc input the output polarity is same as the input polarity. […]
What is the fracture toughness of a material?
What is the fracture toughness of a material? 17.7. “Fracture toughness” describes the resistance of brittle materials to the propagation of flaws under an applied stress, and it assumes that the longer the flaw, the lower is the stress needed to cause fracture. The ability of a flaw to cause fracture depends on the fracture […]
What is a quasi-equilibrium process?
What is a quasi-equilibrium process? In thermodynamics, a quasi-static process (also known as quasi-equilibrium, from the Latin quasi, meaning ‘as if’), is a thermodynamic process that happens slowly enough for the system to remain in internal equilibrium. Any reversible process is a quasi-static one. Why quasi static process is important? Equilibrium in a system in […]
On what factors the efficiency of Carnot engine depends?
On what factors the efficiency of Carnot engine depends? efficiency of the Carnot engine depends on the temperature of the hot and cold reservoirs . Which is more effective way to increase the efficiency of a Carnot engine? Hence efficiency of carnot engine can be increased by a greater amount by increasing the temp. What […]
What is human-computer interaction and why is it important?
What is human-computer interaction and why is it important? Human-computer interaction (HCI) is a multidisciplinary subject that focuses on computer design and user experience. It brings together expertise from computer science, cognitive psychology, behavioural science, and design to understand and facilitate better interactions between users and machines. How human-computer interaction affects the society today? The […]

What is the Zeroth Law of Thermodynamics and how does it lead to the property known as temperature?
What is the Zeroth Law of Thermodynamics and how does it lead to the property known as temperature? The zeroth law of thermodynamics states that if thermal system A is in thermal equilibrium with thermal system B, and thermal system B is in thermal equilibrium with thermal system C, then A must be in thermal […]
Why seismic survey method is widely used in oil and gas exploration?
Why seismic survey method is widely used in oil and gas exploration? Seismic survey is a method used during the exploration phase of oil and gas development. The method gives a first idea of what is present underneath the earth’s surface. The reflected and refracted seismic waves are recorded by a receiver (geophone or hydrophones […]
Has anyone ever died from turbulence?
Has anyone ever died from turbulence? Each year, approximately 58 people in the United States are injured by turbulence while not wearing their seat belts. From 1980 through June 2004, U.S. air carriers had 198 turbulence accidents*, resulting in 266 serious injuries and three fatalities. Can a plane be brought down by turbulence? TLDR – […]
