Q2. Can you explain the difference between thermoplastics and thermosetting plastics? (Materials Science)

Thermoplastics and thermosetting plastics are two major types of polymers with distinct properties and applications. Here’s how they differ:

Property	Thermoplastics	Thermosetting Plastics
Heat Responsiveness	Can be heated and shaped multiple times.	Cannot be reshaped once cured.
Molecular Structure	Linear or branched chains that soften when heated.	Cross-linked structure that becomes rigid once set.
Recyclability	Can be recycled as they can be remelted.	Typically not recyclable due to their inability to be remelted.
Examples	Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC).	Epoxy, Phenolic, and certain polyurethanes.
Applications	Packaging, containers, toys, and automotive parts.	Circuit boards, adhesives, and moldings for high heat applications.

Q3. How do you ensure your designs comply with industry standards and regulations? (Design & Compliance)

Ensuring design compliance involves a thorough understanding of applicable standards and integrating best practices into the design process. Here’s how I ensure compliance:

• I remain informed about current industry standards and regulations by regularly attending professional development workshops and subscribing to industry publications.
• I actively consult with regulatory bodies and standards organizations during the design phase.
• I employ design checklists that include compliance points to be reviewed at each stage of design.
• I engage in peer reviews and third-party audits to validate compliance.
• I utilize compliance management software when applicable to track changes in standards and analyze the impact on ongoing projects.

Q4. Describe your experience with 3D CAD software. Which one do you prefer and why? (Design & Software Proficiency)

I have extensive experience with multiple 3D CAD software packages. Throughout my career, I have worked with AutoCAD, SolidWorks, and PTC Creo. Each software has its strengths, but my personal preference is SolidWorks for the following reasons:

Q6. Explain the concept of ‘factor of safety’ in design. (Safety & Design Principles)

The concept of factor of safety (FoS), also known as safety factor, is a design principle used to provide a safety margin in the engineering design of products, structures, or systems. It is a ratio that compares the actual strength of a material or system to the maximum expected load or stress it will endure during operation. This ensures that the item can support a greater load than what is anticipated in normal usage, accounting for uncertainties in load estimations, material defects, and future degradation.

The factor of safety is defined as:

Factor of Safety (FoS) = Strength of Material or Component / Expected Load or Stress

Here’s why it’s important:

• Uncertainties: It accounts for possible inaccuracies in the design process, such as calculation errors or unknown load conditions.
• Material Properties: Materials may have variations in strength due to manufacturing processes, impurities, or inconsistencies.
• Load Estimations: The actual loads experienced might exceed the predicted or theoretical loads due to unexpected conditions or uses.
• Degradation: Materials can weaken over time due to wear, fatigue, corrosion, or other environmental factors.

The selected value for the factor of safety is often guided by industry standards, regulations, and past experiences. It must balance safety and economy; a very high FoS can result in an unnecessarily heavy and expensive product, while a low FoS might compromise safety.

Q7. How do you approach the troubleshooting of a mechanical system? (Troubleshooting & Problem-Solving)

When approaching the troubleshooting of a mechanical system, it’s important to follow a structured and logical process. Here is a list of steps that are typically involved:

• Identify the Symptoms: Gather information about the problem, including any abnormal sounds, vibrations, leaks, or performance issues.
• Define the Problem: Clearly understand what is wrong with the system by comparing its current behavior to the expected performance.
• Analyze the Causes: Investigate potential causes for the problem, which could be mechanical failures, incorrect settings, lack of maintenance, or external factors.
• Plan the Approach: Devise a plan that prioritizes potential causes based on likelihood and ease of testing or rectification.
• Isolate the Problem: Through testing and elimination, narrow down the exact cause of the issue.
• Repair or Replace: Once the problem is isolated, decide whether to repair the faulty component or replace it.
• Test and Confirm: After the repair, thoroughly test the system to ensure that the problem is resolved and no new issues have arisen.
• Document the Process: Keeping records of the troubleshooting process and solution can aid in future troubleshooting and improve preventive maintenance.
