Bahwan Engineering Mechanical Engineer Interview Questions and Answers for Experienced

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

The project lifecycle is the series of phases a project goes through from initiation to completion.

• Initiation: Define project goals, scope, and stakeholders

• Planning: Create a detailed project plan, schedule, and budget

• Execution: Implement the project plan and deliver the project

• Monitoring and Controlling: Track progress, manage changes, and ensure quality

• Closing: Finalize all project activities and hand off deliverable

Model reviews typically include checking for accuracy, completeness, consistency, and compliance with standards.

• Checking accuracy of dimensions and specifications

• Ensuring completeness of all required components and features

• Verifying consistency in design and documentation

• Confirming compliance with industry standards and regulations

The typical deliverables of a project engineer include design drawings, technical specifications, project schedules, cost estimates, and progress reports.

• Design drawings: detailed plans and schematics for construction or manufacturing

• Technical specifications: detailed requirements for materials, equipment, and processes

• Project schedules: timelines for completing tasks and milestones

• Cost estimates: budget projections fo...read more

Motor starters are used to control the starting and stopping of motors in various applications.

• Motor starters help protect motors from overloads and short circuits.

• They provide a convenient way to start and stop motors remotely.

• Motor starters can also provide under-voltage and over-voltage protection to the motors.

• Examples of applications include industrial machinery, HVAC systems, and water pumps.

The power triangle represents the relationship between real power, reactive power, and apparent power in an AC circuit.

• The power triangle is a visual representation of the relationship between real power (P), reactive power (Q), and apparent power (S) in an AC circuit.

• Real power (P) is the actual power consumed by the circuit and is measured in watts (W).

• Reactive power (Q) is the power that flows back and forth between...read more
