Tata Steel Junior Engineer Interview Questions, Process, and Tips

Q1. What is 2nd law of thermodynamics
Ans. 
The 2nd law of thermodynamics states that entropy in an isolated system always increases over time, leading to energy dispersal.
• Entropy is a measure of disorder or randomness in a system.

• Heat naturally flows from hot to cold objects, not the other way around (e.g., ice melting in a warm drink).

• In any energy transfer, some energy becomes unavailable for doing work (e.g., car engines lose heat).

• The law implies that perpe...read more

Q2. Which material has highest thermal conductivity
Ans. 
Silver has the highest thermal conductivity among all materials, making it ideal for various thermal applications.
• Silver has a thermal conductivity of about 406 W/m·K.

• Copper is the second highest with a thermal conductivity of approximately 385 W/m·K.

• Aluminum follows with a thermal conductivity of around 237 W/m·K.

• These materials are commonly used in electronics and heat exchangers due to their efficient heat transfer

Q3. What is brittleness
Ans. 
Brittleness is a material property characterized by a tendency to fracture without significant deformation.
• Brittle materials absorb little energy before fracture, e.g., glass and ceramics.

• Brittleness is often contrasted with ductility, where ductile materials can deform significantly before breaking, e.g., metals.

• Factors influencing brittleness include temperature, material composition, and microstructure.

• Common exampl...read more

Q1. What are the different types of gearbox?
Ans. 
Different types of gearboxes include manual, automatic, CVT, DCT, and sequential gearboxes.
• Manual gearbox: Requires manual shifting of gears by the driver.

• Automatic gearbox: Shifts gears automatically without driver input.

• CVT (Continuously Variable Transmission): Offers seamless gear ratio changes.

• DCT (Dual Clutch Transmission): Utilizes two clutches for faster gear shifts.

• Sequential gearbox: Gears are selected in sequ

Q2. Define heat treatment ?
Ans. 
Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.
• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and other properti...read more

Q4. Difference between angle of projections in engineering drawing.
Ans. 
Angle of projections in engineering drawing refer to the angles at which an object is viewed in a 2D representation.
• Angle of projection in engineering drawing is the angle at which the object is viewed from the observer's position.

• There are two types of angles of projection - First Angle Projection and Third Angle Projection.

• In First Angle Projection, the object is placed in the first quadrant and the plane of projecti...read more

Q1. Induction motor working
Ans. 
Induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
• A rotating magnetic field is produced in the stator which induces a current in the rotor

• The current in the rotor creates a magnetic field which interacts with the stator field, causing the rotor to rotate

• The speed of the rotor is slightly less than the speed of the stator field, known as slip

• Induction...read more
