Question

After creating a decision matrix for two types of materials used to design a safety belt, an engineer assigns a weight of 4 to nylon for thickness and a weight of 5 to polyester for thickness. The engineer also assigns a weight of 4 to nylon for strength and a weight of 3 to polyester for strength. Polyester is more expensive than nylon. Select the statement that describe which material would be preferable to use for the safety belt if cost is prioritized as a criterion. Nylon would be preferable to use because it is thicker than polyester.

B
Nylon would be preferable to use because it is stronger than polyester.
C
Nylon would be preferable to use because it is less expensive than polyester.
D
Polyester would be preferable to use because it is thicker than nylon.
E
Polyester would be preferable to use use because it is stronger than nylon.
F
Polyester would be preferable to use because it is less expensive than nylon.

Answer 1

Nylon is the preferable choice because it is less expensive than polyester when cost is the primary factor in selecting a material for safety belts.

Step-by-step explanation:

If cost is prioritized as a criterion for selecting a material for the safety belt, the answer to which material would be preferable is C: Nylon would be preferable to use because it is less expensive than polyester. While the decision matrix shows that nylon is given a weight of 4 for thickness and strength whereas polyester is given a weight of 5 for thickness and 3 for strength, these factors are secondary if cost is the main concern. Polyester is indeed utilized in a wide variety of applications due to its durability and resistance, however, it is also more costly. Nylon, on the other hand, is known for being a cost-effective and versatile material with a history of use in military supplies and a range of products from toothbrushes to women's stockings, known as "nylons".
