The specific gravity of steel is around 7.85.
Specific gravity is a measure of the density of a material compared to the density of water.
Steel has a specific gravity of approximately 7.85, which means it is about 7.85 times denser than water.
Specific gravity is a unitless value that helps in comparing the density of different materials.
One Newton is equal to the force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
One Newton is equivalent to 1 kg*m/s^2.
It is named after Sir Isaac Newton, a famous physicist and mathematician.
Commonly used in physics to measure force.
For example, the weight of an apple is approximately 1 Newton.
250 in IS 2062 material refers to the minimum yield strength in MPa of the steel material.
250 is the minimum yield strength in MPa specified in IS 2062 material standards.
It indicates the amount of stress that the material can withstand before permanent deformation.
Higher yield strength values indicate stronger materials suitable for structural applications.
Fasteners grade used depend on the specific application and requirements of the project.
Fasteners grades can range from low-grade steel to high-grade stainless steel or titanium.
Common fastener grades include Grade 2, Grade 5, and Grade 8 for steel fasteners.
In corrosive environments, stainless steel fasteners like 18-8 or 316 are often used.
For high temperature applications, fasteners made from materials like Inconel
ERW pipe stands for Electric Resistance Welded pipe, a type of steel pipe made by welding the edges of a steel strip or coil together.
ERW pipe is made by forming a flat strip of steel into a cylindrical shape and then welding the edges together using a high-frequency electrical current.
It is commonly used in various industries for transporting gas, oil, water, and other fluids.
ERW pipes are known for their high strengt...

The HashMap class is used to represent key-value pairs in Java.
HashMap is a part of the Java Collections Framework.
It allows null values and only one null key.
It provides constant-time performance for basic operations like get and put.
Example: HashMap<String, Integer> map = new HashMap<>();
Abstraction is the process of simplifying complex systems by focusing on essential details and hiding unnecessary complexities.
Abstraction allows us to create models or representations of real-world objects or systems in software.
It helps in managing complexity by breaking down a system into smaller, more manageable parts.
Abstraction provides a level of indirection, allowing changes to be made in one part of the system...
try-catch is used in Java to handle exceptions and prevent program crashes.
try-catch blocks are used to catch and handle exceptions that may occur during program execution.
It allows the program to gracefully handle errors and prevent the program from crashing.
The try block contains the code that may throw an exception, and the catch block handles the exception.
Multiple catch blocks can be used to handle different types...
The statement to use for selecting based on integer inputs is the 'switch' statement.
The 'switch' statement allows for multiple cases to be evaluated based on the value of an integer input.
Each case represents a possible value of the input, and the corresponding code block is executed if the value matches.
The 'switch' statement also provides a 'default' case which is executed if none of the cases match the input value.

I applied via Campus Placement and was interviewed in Oct 2020. There was 1 interview round.
I applied via Approached by company and was interviewed in Aug 2021. There were 2 interview rounds.
Quant focussed Case Study (be prepared for calculations)
I applied via Company Website and was interviewed before Oct 2020. There was 1 interview round.
I appeared for an interview in Mar 2017.
To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes, which is 2 fishes.
To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).
To find the number of fishes to be removed, divide the difference by 1% (2 fishes).
Therefore, 50 fishes have to be removed to make the red fishes 98%.
