Navayuga Engineering Company Interview Questions, Process, and Tips

OPM stands for Optimum Moisture Content. If moisture content in soil is 20%, it will be at its ideal level for compaction.

• OPM is the moisture content at which soil is most workable and compactable.

• At 20% moisture content, soil will be at its optimum level for compaction.

• Higher or lower moisture content can lead to poor compaction and stability issues.

CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique) are project management tools used to plan and schedule tasks.

• CPM is a deterministic model that calculates the longest path through a project's tasks to determine the minimum project duration.

• PERT is a probabilistic model that uses three time estimates (optimistic, pessimistic, and most likely) to calculate the expected project duration.

• Both C...read more

Density of steel, wood, and cement varies due to their composition and structure.

• Steel has a density of around 7850 kg/m^3

• Wood has a density ranging from 400-800 kg/m^3 depending on the type of wood

• Cement typically has a density of 1440 kg/m^3

T/F stands for Transformer, which is a device used to transfer electrical energy between two or more circuits through electromagnetic induction.

• T/F stands for Transformer, a device that changes the voltage of an alternating current in an electrical circuit.

• Transformers are essential in power distribution systems to step up or step down voltage levels as needed.

• They work on the principle of electromagnetic induction, wh...read more

Megger is a portable instrument used to measure the insulation resistance of electrical equipment.

• Megger is used to test the insulation resistance of wires, cables, transformers, and electrical motors.

• It helps in identifying any insulation breakdown or faults in the equipment.

• The instrument applies a high voltage to the equipment and measures the resistance to current flow.

• Megger readings are typically measured in mega

A multimeter is a versatile tool used to measure voltage, current, and resistance in electrical circuits.

• A multimeter typically has a digital display to show the measured values

• It can measure AC and DC voltage, current, resistance, and sometimes other parameters like capacitance and frequency

• Multimeters have different settings for different types of measurements, such as voltage, current, and resistance

• They often have ...read more
