Tata Steel Assistant Engineer Interview Questions, Process, and Tips

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.

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 crucia...read more

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 a...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

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 r...read more

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 tr...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 ...read more
