When fully tempered glass is broken, it breaks into what kind of pieces?
-
Long shards
-
Small granules
-
A mix of small and large pieces
Correct Answer
A. Small granulesExplanation
When fully tempered glass is broken, it breaks into small granules. This is because fully tempered glass undergoes a special heating and cooling process that creates tension on the surface of the glass. When broken, this tension causes the glass to shatter into small, relatively harmless pieces instead of large, sharp shards. This is a safety feature of tempered glass, as the small granules are less likely to cause serious injury compared to larger pieces or shards.Rate this question:

What type of construction requires exterior walls to be constructed of noncombustible materials and allows interior elements such as floors, roofs, and interior nonbearing framing to be constructed of small-dimension wood or metal stud systems?
-
Type I
-
Type II
-
Type III
Correct Answer
A. Type IIIExplanation
Type III construction requires exterior walls to be constructed of noncombustible materials, such as concrete or masonry, to provide fire resistance. However, it allows interior elements like floors, roofs, and interior nonbearing framing to be constructed of small-dimension wood or metal stud systems. This type of construction is commonly used in residential buildings, where the exterior walls need to be fire-resistant but the interior elements can be made of lighter materials for cost-effectiveness and ease of construction.Rate this question:

Barns, livestock shelter, carports, towers, and sheds are all included in what occupancy classification?
-
Storage occupancy
-
Special permit occupancy
-
Utility/miscellaneous occupancy
Correct Answer
A. Utility/miscellaneous occupancyExplanation
Barns, livestock shelter, carports, towers, and sheds are all structures that serve various utility purposes and do not fall under any specific occupancy classification such as residential or commercial. They are not primarily used for storage, as storage occupancy would typically refer to dedicated storage facilities. Therefore, the most appropriate classification for these structures would be utility/miscellaneous occupancy, as they serve a range of utility purposes.Rate this question:

Which of the following is a disadvantage of wood as a building material?
-
It lacks structural strength
-
Weather changes its shape and size
-
It is easily damaged by external forces
Correct Answer
A. Weather changes its shape and sizeExplanation
Wood is a natural material that is prone to changes in shape and size due to weather conditions. It expands and contracts with fluctuations in temperature and humidity, which can lead to warping, twisting, or cracking. This can affect the structural integrity of wood as a building material and may require additional maintenance and repairs over time. Therefore, the disadvantage of wood as a building material is that it is susceptible to weather-induced changes in shape and size.Rate this question:
