I applied via Naukri.com and was interviewed before Jan 2023. There were 2 interview rounds.
The characteristic strength of concrete is influenced by the water-cement ratio.
The water-cement ratio is the ratio of the weight of water to the weight of cement used in the concrete mix.
A lower water-cement ratio generally results in higher characteristic strength.
A higher water-cement ratio can lead to lower characteristic strength and reduced durability.
The water-cement ratio affects the hydration process and the o...
The density of DI, MS, and HDPE pipes varies depending on their composition and manufacturing process.
Density is a measure of mass per unit volume.
DI (Ductile Iron) pipes have a density of approximately 7.2 g/cm³.
MS (Mild Steel) pipes have a density of around 7.85 g/cm³.
HDPE (High-Density Polyethylene) pipes have a density ranging from 0.93 to 0.97 g/cm³.
The density of pipes is an important factor in determining their ...
Workability refers to the ease of handling and placing concrete, while durability refers to its ability to withstand environmental and service conditions.
Workability is influenced by factors such as water content, aggregate size, and admixtures.
Workable concrete can be easily mixed, transported, and placed without segregation or excessive bleeding.
Durability is affected by factors like the water-cement ratio, cement co...
The pressure range of DI and HDPE pipes varies depending on their size and application.
The pressure range of DI (Ductile Iron) pipes typically ranges from 150 psi to 350 psi.
HDPE (High-Density Polyethylene) pipes have a pressure range of 100 psi to 300 psi.
The pressure rating of pipes also depends on their diameter and wall thickness.
For example, a 4-inch DI pipe with a wall thickness of 0.25 inches may have a pressure...

The question is about symbols, types of pole, principle of rectifier and its working.
Symbols used in electrical engineering include resistor, capacitor, inductor, etc.
Types of poles include north and south poles in magnets and positive and negative poles in batteries.
The principle of rectifier is to convert AC to DC.
Rectifiers can be half-wave or full-wave.
Working of rectifier involves the use of diodes to allow curren

Understanding crane lifting capacity is crucial for safe and efficient project execution.
Crane capacity is determined by the type of crane and its configuration.
For example, a tower crane can lift heavier loads than a mobile crane due to its fixed base.
The lifting capacity decreases as the radius increases; for instance, a crane may lift 10 tons at 10 meters but only 5 tons at 20 meters.
Load charts provided by manufact...
Effective interaction and movement of major components ensure project success and efficiency in engineering tasks.
Understand the specifications of each component to ensure compatibility.
Utilize CAD software for precise modeling and visualization of component interactions.

The number of cranes in a crane package depends on project size, load requirements, and site conditions.
Typically, one crane is sufficient for small to medium projects.
For larger projects, multiple cranes may be needed for efficiency.
Example: A high-rise building may require 2-3 cranes for simultaneous operations.
Consideration of crane type (tower, mobile) affects the number needed.
Site layout and logistics can also di
Tensioning and torquing tools ensure proper fastening and load distribution in engineering projects.
Torque Wrench: Used to apply a specific torque to fasteners, ensuring they are tightened to the correct specification.
Tensioning Tool: Devices like hydraulic tensioners that apply a precise amount of tension to bolts, often used in large structures.
Torque Angle Gauge: Measures the angle of rotation after a fastener has b...
MCC (Motor Control Center) work process involves design, installation, and maintenance of electrical control systems for motors.
Design: Create layout and specifications for the MCC based on project requirements.
Installation: Assemble and install MCC components like circuit breakers, contactors, and control panels.
Testing: Conduct functional tests to ensure all components operate correctly and safely.
Maintenance: Regula...
MCC closing involves safely shutting down a Motor Control Center, ensuring equipment and personnel safety.
1. Ensure all equipment is in a safe state before closing the MCC.
2. Notify all personnel involved in the operation about the MCC closure.
3. Follow lockout/tagout (LOTO) procedures to prevent accidental re-energization.
4. Gradually reduce load on the MCC by shutting down connected equipment.
5. Monitor voltage and c...
