Difficulty: Easy
Correct Answer: Incorrect
Explanation:
Introduction / Context:
Knowing the standard section types is essential for clear communication. Half sections, offset sections, broken-out sections, aligned sections, revolved and removed sections each have distinct purposes. This question probes the correct definition of a half section versus the less common term “quarter section.”
Given Data / Assumptions:
Concept / Approach:
Terminology matters: the hallmark of a half section is the combination of interior details (sectioned) and exterior silhouette (unsectioned) within the same view. Mislabeling this as a quarter section can mislead fabrication or inspection teams.
Step-by-Step Solution:
Recall the half section: one half sectioned, one half exterior.Match the described property to the correct term (half section).Evaluate the claim that this defines a quarter section.Conclude the statement is incorrect.
Verification / Alternative check:
Typical textbook figures explicitly label such views as “half section,” showing a symmetrical part like a bearing housing with one half hatched and one half not.
Why Other Options Are Wrong:
“Correct” would misname a standard view. Conditional options about symmetry, hatch spacing, or offset cutting do not alter the definition of a half section.
Common Pitfalls:
Using nonstandard terms on drawings; swapping meanings of half and broken-out sections; omitting the centerline that divides the two halves in a half section.
Final Answer:
Incorrect
