Q86. signalling interlocking principles
Signalling interlocking principles ensure safe train movements by preventing conflicting routes.
Interlocking is a safety system that prevents conflicting train movements
It ensures that only one train can occupy a section of track at a time
Interlocking principles are based on track layout and signalling equipment
The system uses logic circuits to control signals and points
Examples of interlocking systems include mechanical, electrical, and electronic
Interlocking is a critical c...read more
Q87. Any cultural issue ?
Yes, cultural issues can arise in various contexts.
Cultural issues can arise in workplaces, schools, and communities.
Examples include language barriers, discrimination, and cultural misunderstandings.
Cultural issues can impact communication, collaboration, and overall harmony.
Addressing cultural issues requires cultural sensitivity, education, and open dialogue.
Q88. What's stress, how to calculate
Stress is a measure of the internal forces within a material that resist deformation.
Stress is calculated by dividing the force applied to an object by the cross-sectional area of the object.
The formula for stress is Stress = Force / Area.
Stress is typically measured in units of force per unit area, such as Pascals (Pa) or pounds per square inch (psi).
Q89. What's strain, how to calculate
Strain is a measure of deformation or change in shape of a material, calculated as the change in length divided by the original length.
Strain is a dimensionless quantity, typically expressed as a percentage or in decimal form.
It is calculated using the formula: Strain = (Change in length) / (Original length)
There are different types of strain such as tensile strain, compressive strain, and shear strain.
Strain can be caused by forces acting on a material, such as stretching, c...read more
Q90. Document controller work
Document controllers manage the storage, organization, and retrieval of company documents.
Maintain document control procedures
Ensure documents are up-to-date and accurate
Manage document storage and retrieval systems
Coordinate with other departments to ensure document flow
Maintain confidentiality and security of documents
Q91. What is cable route plan?
Q92. reference tracker to point to memory location
A reference tracker is used to point to a specific memory location.
A reference tracker is a variable that stores the memory address of another variable.
It is commonly used in programming languages like C++ and Java.
For example, in Java, the 'this' keyword is a reference tracker that points to the current object.
Reference trackers are useful for passing variables by reference instead of by value.

Q94. OSI Layers definition and functions
OSI Layers are a model for network communication that defines the functions of each layer.
OSI Layers are a 7-layer model for network communication.
Each layer has a specific function and communicates with the layers above and below it.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Examples of functions include: Physical layer handles the transmission of raw data, Transport layer ensures reliable data transfer, and Application la...read more
Q95. Oops concepts? interface vs abstract?,
Interface and abstract are both OOP concepts. Interface defines a contract, abstract class provides partial implementation.
Interface is a blueprint for classes to implement, while abstract class is a class that cannot be instantiated but can be subclassed.
Interface can have only method signatures, while abstract class can have both method signatures and concrete methods.
A class can implement multiple interfaces, but can only inherit from one abstract class.
Interfaces are used...read more
Q96. draw 1st angle and 3rd angle projection
First angle and third angle projections are two common methods used in technical drawing to represent 3D objects on a 2D plane.
First angle projection: object is placed in the first quadrant, with the front view on the top and the side view on the right.
Third angle projection: object is placed in the third quadrant, with the front view on the bottom and the side view on the left.
Both projections involve projecting the object onto a plane parallel to the viewing plane.
First ang...read more
Q97. Stress strain diagram of mild steel
Stress strain diagram of mild steel shows the relationship between stress and strain during deformation.
Stress strain diagram of mild steel typically shows a linear elastic region, followed by a yield point, plastic deformation, and ultimate failure.
The linear elastic region represents the material's ability to return to its original shape after the stress is removed.
The yield point is where the material begins to deform plastically.
Plastic deformation occurs beyond the yield...read more
Q98. How to analysis variance
Variance analysis involves comparing actual results to budgeted or expected results to identify discrepancies.
Calculate the difference between actual and budgeted figures for each line item
Identify the reasons for the variances (e.g. price changes, volume changes, mix changes)
Analyze the impact of variances on overall performance and make recommendations for improvement
