TCS Interview Questions and Answers

2-stroke engines have one power stroke per revolution, while 4-stroke engines have one power stroke every two revolutions.

• 2-stroke engines have a simpler design with fewer moving parts compared to 4-stroke engines.

• 2-stroke engines require a fuel-oil mixture for lubrication, while 4-stroke engines have a separate oil reservoir.

• 2-stroke engines are lighter and produce more power for their size, but are less fuel efficient than 4-stroke engines.

• Examples: 2-stroke engines are com...read more

IC engines are internal combustion engines where fuel is burned internally, while EC engines are external combustion engines where fuel is burned externally.

• IC engines have combustion happening inside the engine, like in a car engine.

• EC engines have combustion happening outside the engine, like in a steam engine.

• IC engines are more common in vehicles, while EC engines are used in power plants.

• IC engines are more efficient in terms of power output, while EC engines are more ef...read more

Engineering is a field that involves the application of scientific and mathematical principles to design and create structures, machines, systems, and processes.

• Engineering encompasses various disciplines such as civil, mechanical, electrical, and chemical engineering.

• Engineers use their knowledge to solve complex problems and improve existing technologies.

• Examples of engineering projects include designing bridges, developing new medical devices, and creating sustainable ener...read more

Joule's law relates to the heat produced by a current passing through a resistor, while Newton's laws describe the relationship between an object's motion and the forces acting on it.

• Joule's law states that the heat produced by a current passing through a resistor is directly proportional to the square of the current and the resistance of the resistor. It can be expressed as Q = I^2 * R, where Q is the heat produced, I is the current, and R is the resistance.

• Newton's laws of ...read more

Gear terminology includes pitch, module, pressure angle, and types of gears include spur, helical, bevel, worm, etc.

• Gear terminology includes pitch, module, pressure angle, and tooth profile.

• Types of gears include spur, helical, bevel, worm, rack and pinion, etc.

• Spur gears have straight teeth and are used for parallel shafts.

• Helical gears have angled teeth for smoother operation.

• Bevel gears are used for intersecting shafts.

• Worm gears have a screw-like appearance and are used ...read more
