I appeared for an interview before Jul 2016.
The deflection of a simply supported beam refers to the amount of bending or displacement that occurs when a load is applied.
The deflection of a simply supported beam depends on factors such as the length of the beam, the type of load applied, and the material properties of the beam.
It can be calculated using various methods such as the Euler-Bernoulli beam theory or finite element analysis.
The deflection of a simply s...

There are various types of CCTV cameras such as dome, bullet, PTZ, thermal, and covert cameras.
Dome cameras are commonly used for indoor surveillance and have a wide-angle view.
Bullet cameras are weatherproof and have a longer range than dome cameras.
PTZ cameras can pan, tilt, and zoom to cover a larger area.
Thermal cameras use heat signatures to detect movement and are often used in low-light environments.
Covert camer...
CCTV stands for Closed Circuit Television. It is a system of video cameras used for surveillance and security purposes.
CCTV cameras are commonly used in public places like banks, airports, and shopping malls.
They can also be used in homes and businesses for security purposes.
CCTV footage can be used as evidence in criminal investigations.
The use of CCTV has raised concerns about privacy and civil liberties.

Gears are mechanical components that transmit power and motion between rotating shafts. There are various types of gears.
Spur gears are the most common type and have straight teeth.
Helical gears have angled teeth and provide smoother operation.
Bevel gears transmit power between shafts that are not parallel.
Worm gears have a screw-like thread and are used for high reduction ratios.
Planetary gears have a central gear tha...
Stress is the force applied per unit area, while strain is the deformation caused by stress.
Stress is measured in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m²).
Strain is the ratio of the change in length or shape of an object to its original length or shape.
Stress and strain are related by the material's modulus of elasticity, which is a measure of how much the ma...
A centrifugal pump is a mechanical device that uses centrifugal force to transport fluids. There are two types: radial and axial.
Centrifugal pumps are commonly used in industrial and domestic applications.
Radial pumps have a volute casing and are used for low flow and high head applications.
Axial pumps have a propeller and are used for high flow and low head applications.
Centrifugal pumps are easy to install and mainta...
SI and CI engines are types of internal combustion engines used in vehicles and machinery.
SI engine stands for Spark Ignition engine, also known as gasoline engine.
CI engine stands for Compression Ignition engine, also known as diesel engine.
SI engines use a spark plug to ignite the fuel-air mixture, while CI engines use compression to ignite the fuel.
SI engines are commonly used in cars, motorcycles, and small machine...
Knocking is a phenomenon where the air-fuel mixture in the engine cylinder ignites spontaneously before the spark plug fires.
Knocking is also known as detonation or pinging.
It can cause engine damage if not addressed.
It occurs when the air-fuel mixture in the cylinder ignites prematurely due to high pressure and temperature.
It can be caused by low-quality fuel, incorrect ignition timing, or engine overheating.
To preven...

I applied via Campus Placement and was interviewed before Dec 2020. There was 1 interview round.
The question covers power factor of transformer, types of DC machine, working principle of AC alternator, and DC motors.
Power factor of a transformer is the ratio of real power to apparent power.
Types of DC machines include DC motors and DC generators.
AC alternators work on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
DC motors convert electrical energy into mechanical ...
