10+ Senior Design Engineer Interview Questions and Answers for Freshers

The internal band radius for a rod sheet can be calculated using the formula: radius = thickness / (2 * pi)

• Calculate the internal band radius using the formula: radius = thickness / (2 * pi)

• For a rod sheet with a thickness of 0.3 mm, the internal band radius would be 0.0477 mm

• The total length of 100 meters is not relevant to calculating the internal band radius

Factors considered include functionality, reliability, manufacturability, cost, and user experience.

• Reliability - Will the design consistently perform as expected over its lifespan?

• Manufacturability - Can the design be easily and cost-effectively produced?

• Cost - Is the design cost-effective to produce and maintain?

• User experience - Does the design meet the needs and expectat...read more

Band radius refers to the minimum inside radius that can be achieved in a sheet metal design.

• Band radius is influenced by material thickness, bend angle, and tooling capabilities.

• Factors to consider in sheet metal design include material selection, bend radius, and tolerances.

• Design for manufacturability is crucial to ensure the sheet metal can be produced efficiently and accurately.

The appropriate thickness for sheet metal is determined based on factors like material type, application, structural requirements, and cost.

• Consider the material type and its properties such as strength and flexibility

• Evaluate the application of the sheet metal, whether it will be used for structural support or aesthetic purposes

• Determine the structural requirements such as load-bearing capacity and resistance to deformation

• Take into account cost considerations, as thicker sh...read more

Yes, I am okay with the alwar location.

• I am willing to relocate for the job.

• I have researched the location and am comfortable with it.

• I have no personal or professional commitments that would prevent me from moving.

• I am excited about the opportunity and am ready to start work as soon as possible.

First angle and third angle methods are two different approaches used in engineering drawings to represent the 3D object in 2D.

• First angle method is commonly used in Europe and Asia, where the object is imagined to be in the first quadrant of a Cartesian coordinate system.

• Third angle method is commonly used in North America, where the object is imagined to be in the third quadrant of a Cartesian coordinate system.

• In first angle method, the top view is placed above the front v...read more

Compression members are structural elements subjected to axial compressive forces.

• Compression members are used in buildings, bridges, and other structures to support loads in compression.

• Common examples include columns, struts, and trusses.

• The design of compression members involves considerations such as buckling, stability, and material strength.

Yes, the shift timing of the company is flexible.

• Employees have the option to choose their preferred shift timings based on their work requirements.

• There may be core hours when all employees are expected to be present, but beyond that, flexibility is provided.

• Remote work options may also be available, allowing employees to work outside traditional office hours.

SLD preparation involves selecting appropriate cables based on load requirements, environmental conditions, and safety regulations.

• Consider the load requirements of the system to determine the appropriate cable size and type.

• Take into account environmental factors such as temperature, moisture, and chemical exposure when selecting cables.

• Ensure compliance with safety regulations and standards to prevent hazards and ensure reliability.

• Examples: Use of shielded cables for high ...read more

Slenderness ratio is a measure of a structural element's stability under compression, and codes such as ACI, AISC, and Eurocode are commonly used in design.

• Slenderness ratio is the ratio of the effective length of a column to its radius of gyration.

• Different codes have different criteria for slenderness ratio limits to ensure structural stability.

• Examples of codes used for slenderness ratio calculations include ACI (American Concrete Institute), AISC (American Institute of St...read more

Design challenges include balancing functionality, cost, manufacturability, and aesthetics.

• Balancing functionality with cost constraints

• Ensuring manufacturability and ease of assembly

• Achieving desired aesthetics while meeting performance requirements

Types of fits refer to the different levels of clearance between mating parts in engineering designs.

• Clearance fit: parts are intended to have a gap between them for easy assembly and disassembly (e.g. sliding fit)

• Interference fit: parts are intended to be pressed or hammered together for a tight joint (e.g. press fit)

• Transition fit: parts have a combination of clearance and interference depending on the specific requirements of the design (e.g. force fit)

Angle of projection refers to the angle at which an object is launched into the air.

• Angle of projection affects the range and height of the projectile.

• The optimal angle of projection for maximum range is 45 degrees.

• Different angles of projection result in different trajectories of the object.

• The angle of projection can be calculated using trigonometry.

• Examples: throwing a ball, launching a rocket, kicking a soccer ball.

Strength of material refers to the ability of a material to withstand applied forces without failure.

• Strength of material is typically measured through tensile, compressive, and shear tests.

• Factors affecting strength include material composition, temperature, and loading conditions.

• Examples of materials with high strength include steel, titanium, and carbon fiber.

• Design engineers must consider material strength when selecting materials for a specific application.
