10+ Tata Steel Assistant Engineer Interview Questions and Answers

Bearings are used to reduce friction between two moving parts. There are different types of bearings and each requires specific maintenance.

• Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings are the most common type and require regular lubrication.

• Roller bearings are used for heavy loads and require periodic cleaning and lubrication.

• Plain bearings are simple and require regular lubrication and cleaning.

• Fluid bearings use...read more

Bearings are mechanical components that reduce friction between moving parts and support axial and radial loads.

• Bearings work by allowing two surfaces to roll or slide over each other with minimal friction.

• They are designed to support loads in a specific direction, such as radial or axial.

• There are several types of bearings, including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearing...read more

Bernoulli theorem is a principle that describes the relationship between fluid speed and pressure.

• States that as the speed of a fluid increases, the pressure within the fluid decreases

• Used to explain the lift force generated by an airplane wing

• Applicable to both incompressible and compressible fluids

A lance is a long, pointed weapon used in medieval warfare.

• Lances were typically made of wood or metal.

• They were used by knights on horseback to charge at their enemies.

• The length of a lance varied, but it was usually between 9 and 14 feet long.

• Lances were often decorated with banners or flags to identify the knight carrying it.

• The use of lances declined with the advent of firearms in warfare.

ID fan stands for Induced Draft fan which is used to create negative pressure in a boiler.

• ID fan is used to draw flue gases from the furnace and exhaust them to the atmosphere.

• It helps in maintaining the proper flow of air and gases in the boiler.

• ID fan is typically installed at the outlet of the boiler.

• It is driven by an electric motor or steam turbine.

• The size and capacity of ID fan depend on the size of the boiler and the amount of flue gases produced.

• ID fan plays a crucia...read more

• Safety involves taking precautions to prevent accidents or injuries

• It includes following safety guidelines and procedures

• Safety is important in all aspects of life, including work, home, and leisure activities

• Examples of safety measures include wearing protective gear, using safety equipment, and practicing safe behaviors

• Safety is a shared responsibility and requires cooperation and communication a...read more

Tilt drive is a mechanism used in construction to tilt heavy objects or structures.

• Tilt drive is commonly used in the construction of bridges, buildings, and large machinery.

• It involves the use of hydraulic cylinders or motors to tilt the object or structure.

• The tilt drive system must be carefully designed and engineered to ensure safety and stability.

• Proper maintenance and inspection of the tilt drive system is crucial to prevent accidents and ensure optimal performance.

Silica in main steam line of boiler can cause severe damage and reduce efficiency.

• Silica can lead to the formation of hard deposits on boiler tubes, reducing heat transfer efficiency.

• High levels of silica can also cause erosion and corrosion of boiler components.

• Regular monitoring and control of silica levels in boiler feedwater is essential to prevent damage.

• Treatment methods such as ion exchange or reverse osmosis can be used to remove silica from feedwater.

Design of gears involves selecting appropriate gear type, size, material, and tooth profile for efficient power transmission.

• Gears are used to transmit power and motion between two rotating shafts.

• The gear type and size are selected based on the required speed ratio and torque.

• The material selection depends on the application and operating conditions.

• The tooth profile is designed to ensure smooth and efficient power transmission.

• Common gear types include spur, helical, bevel,...read more

Coal Gross Calorific Value (GCV) is a key parameter in determining the efficiency of a power plant.

• GCV is a measure of the amount of heat released when a unit mass of coal is combusted.

• It is typically expressed in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (Btu/lb).

• Higher GCV coal is preferred in power plants as it produces more energy per unit mass.

• The GCV of coal can vary depending on its type, moisture content, and impurities.
