Three types of heat-modified glass are available. List them in order of the strongest to the weakest type. If any two types are of the same strength, mention so.
What will be an ideal response?
(i) Tempered glass, (ii) Heat-soaked glass, and (iii) heat-strengthened glass. Tempered glass and heat-soaked glass
are of the same strength.

Cost increases imposed by design changes introduced at different times during advancing stages of the product life cycle (PLC) usually rise dramatically as the change is introduced later in the life cycle of the product. Though the numbers vary from one industry to another, one cost-increase model looks something like the following:

Hamound Industries designed, developed, and is now manufacturing for sales an improved version of its model GR1 smoke detector system that can be used on high speed trains, such as the TGV (Train à Grande Vitesse in French). The original estimates, developed during the conceptual design stage, are shown below. During the testing stage, a major safety flaw was discovered and significant design changes were made, affecting only the equipment first cost estimate, fortunately. Now, during manufacturing, a significant problem has emerged that makes the internet-connectivity feature difficult to manufacture with the level of required reliability. This change will increase the manufacturing cost per unit by a factor of 5. The initial economic analysis, conducted during the conceptual stage, using the AW value at i = 7% per year, showed very promising results. However, the design changes have affected this positive analysis. Use the original estimates and the PLC cost multipliers summarized above to perform AW analyses for the four stages from conceptual through manufacturing to determine what has happened to the economic viability of the improved product.

The manager of a canned-food processing plant has two labeling machine options. On the basis of a rate of return analysis with a MARR of 20% per year, determine (a) which model is economically better, and (b) if the selection changes, provided both options have a 4-year life and all other estimates remain the same.
