Electrosteel Casting Diploma Trainee Engineer Interview Questions and Answers

Steam in a boiler is generated by heating water to its boiling point. There are various types of boilers, such as fire tube, water tube, and electric boilers.

• Boilers generate steam by heating water to its boiling point

• Types of boilers include fire tube, water tube, and electric boilers

• Fire tube boilers have hot gases flowing through tubes that are surrounded by water

• Water tube boilers have water flowing through tubes that are heated by combustion gases

• Electric boilers use ele...read more

Electricity in power plants is generated through various methods like burning fossil fuels, nuclear reactions, or harnessing renewable sources like wind or solar.

• Burning fossil fuels like coal, oil, or natural gas to heat water and produce steam to turn turbines

• Nuclear reactions in nuclear power plants to generate heat and produce steam

• Harnessing renewable sources like wind turbines or solar panels to convert natural energy into electricity

Unit of strain is dimensionless, mechanical properties include stress, strain, modulus of elasticity, yield strength, ultimate tensile strength, etc.

• Strain is a dimensionless quantity representing the deformation of a material relative to its original size.

• Mechanical properties include stress, strain, modulus of elasticity, yield strength, ultimate tensile strength, etc.

• Units of stress are typically measured in Pascals (Pa) or pounds per square inch (psi).

• Units of strain are ...read more

A cantilever beam is a type of beam that is fixed at one end and free at the other end.

• Cantilever beams are commonly used in construction and engineering projects.

• Examples of cantilever beams include diving boards, balconies, and shelves.

• They are designed to support loads on the free end without any additional support at that end.

The full process of a power plant involves converting fuel into electricity through various stages.

• Fuel (such as coal, natural gas, or nuclear material) is burned to produce heat

• The heat is used to boil water and create steam

• The steam turns a turbine connected to a generator, producing electricity

• The electricity is then sent through transmission lines to homes and businesses

• Waste heat is often captured and used for other purposes to increase efficiency
