Deck 3: Properties of Materials

Question 1

Approximately _____ pollutants identified in very common building materials are known to cause asthma, allergies, cancer, and reproductive and nervous system disorders.

A) 500
B) 600
C) 700
D) 800

Answer 1

A

Question 2

Name some of the materials used frequently in the last few decades that carry risk of contamination.

Answer 2

Certain materials used frequently in the last few decades that carry the risk of contamination include polyvinylchloride (PVC), used in flooring, wall coverings, plumbing, carpet backing, and electronics; formaldehyde products, such as plywood and particle board; synthetic carpets; and sheet vinyl.

Question 3

What are EPPs? Why and when does the federal government mandate their use?

Answer 3

​ EPPS are Environmentally Preferable Products. They are defined by the federal government in Executive Order 13101 as those that have: "a lesser or reduced effect on human health and the environment when compared to competing products that serve the same purpose." The federal government, in an effort to help federal purchasers and simultaneously stimulate market demand for green products and materials, mandates the use of environmentally preferable products in all new federally financed construction projects.

A) hardness
B) fatigue strength
C) ductility
D) impact strength

D) tension

Question 6

____ is the branch of physics that deals with the generation, transmission, and control of sound waves.

A) Acoustics
B) Relativity
C) Electromagnetism
D) Quantum mechanics

Question 7

The modulus of ____ is a proportional constant between stress and strain.

A) force
B) tension
C) elasticity
D) shearing

Question 8

When a material is subjected to a change in ____, it may expand, contract, conduct, or reflect heat.

A) ductility
B) strength
C) permeability
D) temperature

Question 9
