Alpla Diploma Electrical Engineer Interview Questions and Answers

Q1. Different Type of Heat transfer?
Ans. 
Different types of heat transfer include conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between particles. Example: Touching a hot stove.

• Convection: Heat transfer through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation: Heat transfer through electromagnetic waves. Example: Feeling the warmth of the sun.

Q2. What is entropy?
Ans. 
Entropy is a measure of disorder or randomness in a system.
• Entropy is a thermodynamic property that quantifies the amount of energy in a physical system that is not available to do work.

• It is a measure of the number of possible arrangements of the particles in a system.

• Entropy tends to increase in closed systems over time, leading to a state of maximum disorder.

• An example of entropy is the melting of ice into water, wh...read more

Q4. Laws of Thermodynamic with example?
Ans. 
Laws of Thermodynamics explain the behavior of energy in a system.
• First Law: Energy cannot be created or destroyed, only transferred or converted. Example: A car engine converts fuel (chemical energy) into motion (kinetic energy).

• Second Law: Entropy in a closed system always increases, meaning energy tends to disperse. Example: Ice melting into water due to an increase in entropy.

• Third Law: As temperature approaches ab...read more

Q5. What are backward and forward stroke in shaping machine
Ans. 
Backward stroke is the return stroke of the ram in shaping machine, while forward stroke is the cutting stroke.
• Backward stroke is when the ram moves away from the workpiece

• Forward stroke is when the ram moves towards the workpiece to make the cut

• Backward stroke is non-cutting, while forward stroke is cutting

• Backward stroke allows the tool to clear the workpiece, while forward stroke performs the cutting operation
