Jindal Saw Interview Questions and Answers

Q1. What are the different types of gears?
Ans. 
Gears are mechanical components that transmit motion and torque between machines, with various types serving different functions.
• Spur Gears: Straight teeth, used in simple machines like clocks.

• Helical Gears: Angled teeth for smoother operation, found in car transmissions.

• Bevel Gears: Cone-shaped, used to change the axis of rotation, like in hand drills.

• Worm Gears: Screw-like, provide high torque and speed reduction, us...read more

Q2. What is the Otto cycle process?
Ans. 
The Otto cycle is a thermodynamic cycle used in gasoline engines, consisting of four stages: intake, compression, power, and exhaust.
• 1. Intake Stroke: Air-fuel mixture enters the cylinder as the piston moves down.

• 2. Compression Stroke: The piston moves up, compressing the mixture, increasing temperature and pressure.

• 3. Power Stroke: The spark plug ignites the mixture, causing an explosion that pushes the piston down.

• 4....read more

Q3. What are the differences between a two-stroke engine and a four-stroke engine?
Ans. 
Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines require four strokes.
• Two-stroke engines have a simpler design and are lighter, making them suitable for applications like chainsaws and dirt bikes.

• Four-stroke engines are more fuel-efficient and produce less pollution, commonly used in cars and larger machinery.

• In a two-stroke engine, the power stroke occurs every revoluti...read more

Q6. What is Pascal's Law?
Ans. 
Pascal's Law states that pressure applied to a confined fluid is transmitted undiminished in all directions.
• Pressure applied to a fluid in a closed system is transmitted equally in all directions.

• Example: Hydraulic systems, like car brakes, use this principle to amplify force.

• In a hydraulic lift, a small force applied on a small area can lift a heavy load on a larger area.

• This law is fundamental in understanding fluid ...read more
