Q2. How do gas turbine engines work
Ans. 
Gas turbine engines work by compressing air, mixing it with fuel, igniting the mixture, and using the hot exhaust gases to spin a turbine.
• Air is drawn into the engine and compressed by a compressor

• Fuel is injected and mixed with the compressed air

• The mixture is ignited, causing a rapid expansion of gases

• The hot exhaust gases are used to spin a turbine, which drives the compressor and generates thrust

• Examples: Jet engin

Q1. Why the brittle material fail as spiral fracture surface under torsion
Ans. 
Brittle materials fail as spiral fracture surface under torsion due to their inability to deform plastically.
• Brittle materials lack ductility and are unable to deform plastically under stress

• Under torsion, the material experiences shear stress which leads to the formation of spiral fracture surfaces

• The lack of plastic deformation causes the material to fail catastrophically along these spiral paths

• Examples of brittle m...read more

Q2. What is entropy
Ans. 
Entropy is a measure of disorder or randomness in a system.
• Entropy is a thermodynamic property that quantifies the amount of energy in a physical system that is not available to do work.

• It is a measure of the number of possible arrangements of particles in a system.

• Entropy tends to increase in isolated systems over time, leading to a state of maximum disorder or equilibrium.

• An example of entropy is the melting of ice -...read more

Q3. How to find natural frequency practically
Ans. 
Natural frequency can be found practically by conducting modal analysis or using specialized equipment like accelerometers.
• Conduct modal analysis by applying a force or impulse to the structure and measuring the resulting vibrations.

• Use specialized equipment like accelerometers to measure the vibrations of the structure.

• Calculate the natural frequency using the formula: f = 1 / (2π√(k/m)), where f is the natural freque...read more

Q4. What is Fast Fourier transform
Ans. 
Fast Fourier Transform (FFT) is an algorithm used to compute the Discrete Fourier Transform (DFT) of a sequence or signal.
• FFT is used to analyze the frequency content of a signal by decomposing it into its constituent frequencies.

• It is commonly used in signal processing, image processing, audio analysis, and many other fields.

• FFT algorithms are much faster than the naive DFT computation, making it practical for real-ti...read more

Q5. How FFT is different from DFT
Ans. 
FFT is a faster algorithm for calculating DFT
• FFT is faster than DFT in terms of computation time

• FFT uses a divide-and-conquer approach to reduce the number of operations

• DFT computes all frequencies while FFT only computes the frequencies of interest

• FFT is commonly used in signal processing applications
