I applied via Walk-in and was interviewed before Sep 2022. There were 2 interview rounds.
Coal is a fossil fuel formed from plant material that has been subjected to high pressure and heat over millions of years.
Coal is primarily composed of carbon, along with small amounts of other elements like sulfur, hydrogen, oxygen, and nitrogen.
There are different types of coal based on their carbon content and energy value, such as anthracite, bituminous, and lignite.
Coal is used as a fuel for power generation, indu...
TM stands for trademark, a symbol used to indicate that a particular product or service is legally protected.
TM is used to protect logos, brand names, and slogans from being used by others without permission.
It does not provide as much legal protection as a registered trademark (R), but still offers some level of protection.
TM symbol can be used even before a trademark is officially registered.
Example: Nike uses the TM...
The ash content of coal can be determined by burning a sample of coal and measuring the residue left behind.

There are several types of dampings in case of vibration, including viscous damping, hysteretic damping, and structural damping.
Viscous damping: It occurs when a fluid or viscous material is used to dissipate energy and reduce vibration.
Hysteretic damping: It is caused by the internal friction within a material, which converts mechanical energy into heat.
Structural damping: It is inherent in the structure itself and is...

Earthquake effects on structures and design process, including Richter scale and other scales.
Earthquakes can cause various effects on structures, such as shaking, ground rupture, and liquefaction.
The design process for structures takes into account the potential seismic forces and aims to ensure safety.
The Richter scale is a logarithmic scale used to measure the magnitude of an earthquake.
Other scales used for earthqu...
I applied via Campus Placement and was interviewed before Sep 2020. There were 4 interview rounds.
Induction Motor equivalent circuit consists of stator and rotor circuits with mutual induction.
The stator circuit includes three-phase winding and a power source.
The rotor circuit includes rotor winding and a short-circuited conductor.
The mutual induction between stator and rotor circuits causes the rotor to rotate.
The equivalent circuit can be represented using a circuit diagram with resistances, inductances, and mutu...
B-H curve is a graph that shows the relationship between magnetic field strength and magnetic flux density.
B-H curve is used to characterize the magnetic properties of a material.
It is a plot of magnetic flux density (B) versus magnetic field strength (H).
The slope of the curve at any point is the permeability of the material at that point.
The curve can be used to determine the saturation point of a material.
