I applied via Walk-in and was interviewed before Jul 2020. There were 4 interview rounds.
Diesel engines are preferred in heavy vehicles due to their high torque and fuel efficiency.
Diesel engines have higher compression ratios than gasoline engines, resulting in more power and torque.
Diesel fuel has a higher energy density than gasoline, providing better fuel efficiency.
Heavy vehicles require more power and torque to move, making diesel engines a better choice.
Diesel engines also have a longer lifespan and...
CC can refer to several things in different contexts, such as cubic centimeters, carbon copy, credit card, etc.
CC stands for cubic centimeters, a unit of measurement for engine displacement in vehicles.
CC can also mean carbon copy, used in email communication to send a copy of a message to multiple recipients.
In finance, CC can stand for credit card.
CC can also refer to closed captioning, a feature that displays text o...
A four-stroke engine is an internal combustion engine that completes four separate strokes in one cycle.
Intake stroke: Fuel and air enter the combustion chamber.
Compression stroke: The piston compresses the fuel and air mixture.
Power stroke: The spark plug ignites the mixture, causing an explosion that pushes the piston down.
Exhaust stroke: The piston pushes the exhaust gases out of the combustion chamber and out of th...

Mechanical design is the process of creating physical products and systems using engineering principles and techniques.
Involves designing components and assemblies for machines, vehicles, structures, etc.
Requires knowledge of materials, manufacturing processes, and CAD software.
Focuses on functionality, safety, and efficiency of the design.
Examples include designing a car engine, a robotic arm, or a bridge structure.
Shear stress is a type of stress that acts parallel to a surface, causing layers of material to slide past each other.
Shear stress is caused by forces applied parallel to a surface, leading to deformation.
It is calculated as force divided by the area over which the force is applied.
Shear stress is commonly seen in materials like fluids, where layers move at different speeds.
Examples include cutting paper with scissors,...
Categories of strength in machine design include static strength, fatigue strength, impact strength, and toughness.
Static strength: Ability to withstand a constant load without breaking.
Fatigue strength: Ability to withstand repeated loading over time.
Impact strength: Ability to withstand sudden shocks or impacts.
Toughness: Ability to absorb energy and deform without fracturing.
