SIAC SKH India Cabs Manufacturing Diploma Trainee Engineer Interview Questions and Answers

Q1. Engine parts and it's function
Ans. 
Engine parts and their functions
• Piston - moves up and down in the cylinder to compress air-fuel mixture

• Cylinder - houses the piston and allows for combustion

• Crankshaft - converts linear motion of piston into rotational motion

• Camshaft - controls the opening and closing of valves

• Spark plug - ignites the air-fuel mixture in the cylinder

• Valves - control the flow of air and fuel into the cylinder and exhaust gases out

• Connec

Q2. Working of engin and functions and application.
Ans. 
The engine is a mechanical device that converts fuel into mechanical energy to power vehicles or machinery.
• Engines work by burning fuel in a combustion chamber to create high-pressure gases that drive pistons or turbines.

• Functions of an engine include intake, compression, combustion, and exhaust.

• Applications of engines include powering cars, trucks, airplanes, ships, generators, and more.

Q1. Thermodynamic equation and cycle
Ans. 
Thermodynamic equations and cycles are fundamental concepts in engineering.
• Thermodynamic equations describe the relationships between various properties of a system.

• The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• The second law of thermodynamics states that the entropy of an isolated system always increases.

• Common thermodynamic cycles include the Carnot c...read more

Q1. What is first law of thermodynamics
Ans. 
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.
• Energy is a conserved quantity

• It can be transferred between systems or converted from one form to another

• The law is also known as the law of conservation of energy

• It applies to all forms of energy including heat, work, and potential energy

• An example is the energy transfer that occurs when a hot object is pla

Q2. What is Enthalpy
Ans. 
Enthalpy is the sum of internal energy and pressure-volume work done by a system.
• Enthalpy is a thermodynamic property of a system.

• It is represented by the symbol 'H'.

• It is defined as the sum of internal energy and pressure-volume work done by a system.

• Enthalpy change is the difference between the enthalpies of the products and reactants in a chemical reaction.

• Enthalpy is used in various fields including chemistry, phys

Q1. What is Resistor in Electronics?
Ans. 
A resistor is an electronic component that limits the flow of electric current in a circuit.
• Resistors are used to control the amount of current flowing through a circuit.

• They are passive components that dissipate energy in the form of heat.

• Resistors are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• They can be fixed resistors with a specific resistance value or variable resistors th...read more

Q2. What is Transformer ?
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers are used to increase or decrease the voltage levels in electrical power transmission and distribution systems.

• They consist of two or more coils of wire, known as windings, which are wound around a core made of magnetic material.

• The primary winding is connected to the input v...read more
