Vedanta Limited Company Secretary Trainee Interview Questions and Answers

The camshaft and crankshaft have different speeds in an engine.

• The camshaft controls the opening and closing of the engine's valves, while the crankshaft converts the reciprocating motion of the pistons into rotational motion.

• The camshaft rotates at half the speed of the crankshaft in a four-stroke engine.

• For example, if the crankshaft rotates at 6000 revolutions per minute (RPM), the camshaft will rotate at 3000 RPM.

CNC stands for Computer Numerical Control. It is a manufacturing process that uses pre-programmed computer software to control machine tools.

• CNC is a manufacturing process that automates the operation of machine tools.

• It uses computer software to control the movement and operation of the machines.

• CNC machines are widely used in industries such as automotive, aerospace, and electronics.

• G codes are a programming language...read more

Different types of chips in metal cutting include continuous chips, discontinuous chips, and built-up edge chips.

• Continuous chips are formed when the cutting tool continuously removes material from the workpiece.

• Discontinuous chips are formed when the cutting tool intermittently removes material, resulting in segmented chips.

• Built-up edge chips occur when the material being cut adheres to the cutting tool, forming a bu...read more

Discontinuous chips are formed in certain materials during machining processes.

• Discontinuous chips are formed in brittle materials like cast iron, ceramics, and glass.

• These materials have low ductility and tend to fracture during machining.

• The discontinuous chips have a segmented or broken appearance.

• They are characterized by irregular shapes and rough surfaces.

• Examples of materials that form discontinuous chips includ...read more

The lack of high-rise buildings in India can be attributed to various factors such as land availability, building regulations, cultural preferences, and infrastructure limitations.

• Limited availability of land in urban areas restricts the construction of high-rise buildings.

• Building regulations and zoning laws often impose height restrictions and setback requirements.

• Cultural preferences in India often favor low-rise bu...read more

Bernoulli Equation is a fundamental principle in fluid dynamics that relates the pressure, velocity, and height of a fluid.

• It describes the conservation of energy in a fluid system.

• It is used to calculate the flow rate of fluids through pipes and channels.

• It is applicable to both incompressible and compressible fluids.

• It is commonly used in aviation to explain the lift force on an airplane wing.

• The equation is P + 1/2p...read more

Copper loss in a transformer decreases when it operates at half its rated MVA.

• Copper loss is directly proportional to the square of the current flowing through the windings.

• When the transformer operates at half its rated MVA, the current flowing through the windings is reduced.

• As a result, the copper loss in the transformer decreases.

• This reduction in copper loss leads to improved efficiency and lower energy consumptio

A wound rotor induction motor can provide high starting torque and high efficiency.

• Wound rotor induction motors have a higher starting torque compared to squirrel cage induction motors.

• The rotor windings in a wound rotor motor can be connected to external resistors, allowing for higher torque during startup.

• By adjusting the resistance in the rotor circuit, the motor can achieve high efficiency at full load.

• Examples of ...read more

A haul road is a road used for transporting materials, typically in a mining or construction site.

• Haul roads are designed to handle heavy loads and are often unpaved.

• They are used to transport materials such as ore, rock, and dirt.

• Haul roads must be maintained regularly to ensure safety and efficiency.

• Proper drainage is important to prevent erosion and maintain road stability.

• Examples of haul road equipment include hau

A flame safety lamp is a type of lamp used in mining to detect methane gas and prevent explosions.

• It works by creating a flame inside a mesh screen that will go out if methane is present.

• The lamp was invented by Sir Humphry Davy in 1815.

• It was widely used in coal mines in the 19th and early 20th centuries.

• Today, electronic gas detectors have largely replaced flame safety lamps in mining.
