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...
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 -...
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...
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...
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
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.
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.
The valu...

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...
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

I applied via Company Website and was interviewed before Jun 2023. There was 1 interview round.
Major resistance by old method involves using traditional techniques to determine the level of resistance in a material.
Use manual testing methods such as scratch testing or hardness testing to assess resistance
Refer to historical data or records of similar materials for comparison
Consult with experienced professionals who have knowledge of traditional resistance testing methods

I have a systematic approach to fault rectification, starting with identifying the root cause and then implementing a solution.
I begin by gathering information about the problem and analyzing it thoroughly
I then identify the root cause of the issue and prioritize the most critical problems
I develop a plan of action and implement a solution, testing it thoroughly to ensure it is effective
I document the entire process fo...
Our system operates on the 2.4 GHz frequency band.
Our system uses the 2.4 GHz frequency band for communication.
This frequency band is commonly used for Wi-Fi and Bluetooth devices.
It has a range of approximately 30 meters indoors.
The 2.4 GHz band is susceptible to interference from other devices operating on the same frequency.
Our system has been optimized to minimize interference and ensure reliable communication.
