VRC Constructions India Mechanical Engineer Interview Questions and Answers

SFD stands for Shear Force Diagram and BMD stands for Bending Moment Diagram in structural analysis.

• SFD shows the variation of shear force along the length of a beam or structure.

• BMD shows the variation of bending moment along the length of a beam or structure.

• Both diagrams are essential for analyzing the internal forces in a structure.

• They are commonly used in civil and mechanical engineering for designing and analyzi...read more

Thrust forces for beams can be calculated using equations of equilibrium and considering external loads.

• Calculate the sum of all external forces acting on the beam.

• Determine the direction of the forces (compression or tension) based on the beam's support conditions.

• Apply equations of equilibrium to calculate the thrust forces at different points along the beam.

• Consider any distributed loads or moments that may affect t...read more

Maintenance of machineries is important to ensure their optimal performance and prevent breakdowns.

• Regular maintenance helps to identify and fix small issues before they become major problems.

• It increases the lifespan of the machinery and reduces the need for costly repairs or replacements.

• Proper maintenance also ensures the safety of workers who operate the machinery.

• Examples of maintenance tasks include lubrication, ...read more

I maintain a detailed logbook for each machine, including maintenance schedules, repairs, and any upgrades.

• Create a logbook for each machine

• Record maintenance schedules, repairs, and upgrades

• Include dates, details of work done, and any parts replaced

• Regularly update the logbook

• Use digital tools like spreadsheets or specialized software for easier tracking

Types of compressors include reciprocating, rotary, centrifugal, and axial compressors.

• Reciprocating compressors use pistons to compress air or gas.

• Rotary compressors use rotating mechanisms such as screws or vanes.

• Centrifugal compressors use a rotating impeller to create centrifugal force.

• Axial compressors use rotating blades to compress air in a straight line.

• Examples include reciprocating air compressors, rotary scr...read more

The procedure to install centrifugal axial compressors involves proper planning, alignment, assembly, and testing.

• Ensure proper foundation is prepared to support the compressor

• Align the compressor with the piping system for proper flow

• Assemble the compressor components according to manufacturer's instructions

• Test the compressor for performance and efficiency before final installation

Types of pumps include centrifugal, positive displacement, and axial flow pumps.

• Centrifugal pumps: use centrifugal force to move fluid through the pump

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge port

• Axial flow pumps: move fluid parallel to the pump shaft

A lifting plan procedure is a detailed plan outlining the steps and precautions to be taken when lifting heavy objects.

• Identify the weight and dimensions of the object to be lifted

• Determine the appropriate lifting equipment needed

• Assess the location and environment for any obstacles or hazards

• Assign roles and responsibilities to team members involved in the lift

• Communicate clearly and follow the plan step by step

• Conduc...read more

Pumps capacity refers to the maximum flow rate a pump can handle.

• Pumps capacity is typically measured in gallons per minute (GPM) or liters per minute (LPM).

• It is important to consider the required flow rate when selecting a pump for a specific application.

• Factors such as pump size, motor power, and system pressure affect the capacity of a pump.

• For example, a centrifugal pump may have a capacity of 500 GPM, while a dia
