Dr. Hatem Elaydi Engineering Technical English Islamic University of Gaza Feb. 20, 2016 Unit 2: Materials Technology Discussing Quality Issues

Discussing Quality Issues Dr. Hatem Elaydi, IUG, Spring 2016, ENGG This section explains what is meant by quality and to give some examples of technical products/brands, for example cars, work tools, mobile phones, or TVs, that have a reputation for good quality. What makes the products stand out from the competition? Why are they better from a technical standpoint? What is meant by value for money and the issue of cost. For the products mentioned, are prices significantly higher? Is higher quality worth a higher price?

Dr. Hatem Elaydi, IUG, Spring 2016, ENGG

12. In groups, discuss the following questions. 1. ln advertising what hi-tech high-performance situations are often used to promote watches? 2. What messages are they intended to send a bout the quality of products? 3. What quality issues differentiate higher-quality watches from lower-quality ones? 4. What is the difference between describing something as water-resistant and waterproof ? Dr. Hatem Elaydi, IUG, Spring 2016, ENGG

Suggested answers 1. Examples of situations used in advertising include motor racing, water sports such as surfing and diving, and aviation. 2. The intended message is that watches are accurate and are resistant. 3. Higher quality watches keep good time; are resistant to water and shocks; and are made from more expensive, better-looking materials. 4. Describing something as water-resistant suggests it can resist water up to a certain limit, for example to a certain depth or pressure. Describing something as waterproof suggests it gives unlimited protection from water. Dr. Hatem Elaydi, IUG, Spring 2016, ENGG

Q 15. In groups, discuss the key properties and types and grades of the following materials. Give examples of the properties that make each material good or bad for watch-making from a quality perspective Dr. Hatem Elaydi, IUG, Spring 2016, ENGG Materials Steel, glass, aluminum, titanium, gold, plastic, copper, rubber Materials Steel, glass, aluminum, titanium, gold, plastic, copper, rubber Properties water-resistant, abrasion-resistant, corrosion-resistant, shock-resistant, touch, brittle, elastic, durable, heavy, Lightweight, thermally stable Properties water-resistant, abrasion-resistant, corrosion-resistant, shock-resistant, touch, brittle, elastic, durable, heavy, Lightweight, thermally stable

Suggested answers Steel is relatively heavy and very tough. It is pretty scratch-resistant and shock resistant. Mild steel is not very corrosion-resistant but stainless steel has good corrosion resistance and is therefore suitable for watches. Glass is quite heavy and is water-resistant and corrosion-resistant. Ordinary glass is very brittle and has fairly poor shock resistance and scratch resistance, although it is still suitable for watches. Toughened glass is more durable. Aluminum is relatively lightweight and is fairly tough. It has good corrosion resistance. It is therefore suitable for watches. Titanium is exceptionally lightweight and tough and has excellent abrasion resistance. It is also extremely corrosion-resistant and is therefore an excellent watch material. Gold is extremely heavy and pretty tough, although softer grades of gold have quite poor shock resistance and scratch resistance. Gold has excellent corrosion resistance. It is suitable for more expensive, decorative watches. Dr. Hatem Elaydi, IUG, Spring 2016, ENGG
