Ewac Alloys Applications Engineer Interview Questions and Answers

DFMEA stands for Design Failure Mode and Effects Analysis, while DFMA stands for Design for Manufacturability and Assembly.

• DFMEA is a systematic approach to identifying and preventing potential failure modes in a design.

• DFMEA involves analyzing each component of a design to determine potential failure modes, their effects, and the likelihood of occurrence.

• DFMA focuses on designing products that are easy to manufacture ...read more

Design procedures are systematic steps followed to create a product or system.

• Design procedures involve defining requirements and constraints.

• They include brainstorming, concept development, prototyping, testing, and refining.

• Documentation of the design process is essential for future reference.

• Examples include the design procedures followed in creating a new software application or a mechanical device.

Flushing is the process of cleaning out a system by forcing fluid through it, while cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure.

• Flushing involves using a fluid to remove contaminants or debris from a system, such as a hydraulic system or a pipeline.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse, leading t...read more

Materials come in different grades based on their composition, properties, and intended use.

• Materials can be classified into metals, polymers, ceramics, and composites.

• Each material type has different grades based on factors like strength, durability, conductivity, and corrosion resistance.

• Examples include steel grades like 304, 316, and 430, polymer grades like HDPE and PVC, and ceramic grades like alumina and zirconi

Stress is the force applied to a material, while strain is the resulting deformation. Mild steel has a linear stress-strain curve.

• Stress is the force applied to a material per unit area, measured in N/m^2 or Pascals.

• Strain is the resulting deformation of the material, measured as a ratio of the change in length to the original length.

• Mild steel typically has a linear stress-strain curve until it reaches its yield point...read more
