Round 1 - Technical 

(5 Questions)

  • 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...

  • 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 -...

  • Answered by AI
  • 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...

  • 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...

  • Answered by AI
  • 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

Interview Questionnaire 

3 Questions

  • Q1. What is baud rate? How does it affect communication ?
  • Ans. 

    Baud rate is the rate at which data is transmitted over a communication channel.

    • Baud rate is measured in bits per second (bps).

    • Higher baud rates allow for faster data transmission.

    • Baud rate must be set the same on both ends of the communication channel.

    • Incorrect baud rate settings can result in data corruption or loss.

    • Examples of communication channels that use baud rate include UART, SPI, and I2C.

  • Answered by AI
  • Q2. What design Issues you faced in your Masters project ?
  • Q3. How I2C communication protocol works what things needs to be taken care while designing for I2C peripheral ,pull-up resistors etc
  • Ans. 

    I2C is a serial communication protocol used to connect multiple devices with two wires. Pull-up resistors are necessary for proper communication.

    • I2C uses a master-slave architecture where the master initiates communication.

    • Each device on the bus has a unique address assigned to it.

    • Data is transmitted in packets with a start and stop bit.

    • Pull-up resistors are necessary to ensure proper voltage levels on the bus.

(2 Questions)

  • Q1. Define the factor of safety?
  • Ans. 

    Factor of safety is a design parameter that accounts for uncertainties in material properties and loading conditions.

    • Factor of safety is the ratio of the maximum stress a material can withstand to the maximum stress it is subjected to in a given application.

    • It ensures that the structure or component will not fail under normal operating conditions.

    • Higher factor of safety values indicate a more conservative design approa...

  • Answered by AI
  • Q2. What is tolerance?
  • Ans. 

    Tolerance refers to the allowable variation in dimensions or properties of a part or product.

    • Tolerance is important in engineering to ensure proper fit and function of components.

    • It is typically specified as a range of acceptable values, such as +/- 0.1mm.

    • Tolerance can be applied to dimensions, material properties, surface finish, etc.

    • For example, a hole may have a tolerance of +/- 0.05mm to allow for proper alignment
