Question

How many consecutive measurements can be shown on a diagonal scale?

• A. 3
• B. 4
• C. 2
• D. 5

Hint:

Diagonal scales allow precise measurements by dividing units into three levels: main units, subdivisions, and further fractions.

Answer 1

The Correct Option is A

Explaining diagonal scale
Step 1: A diagonal scale is a drafting tool used in technical drawing to measure lengths with high precision, dividing units into smaller subdivisions.
Understanding measurements
Step 2: A diagonal scale typically shows three consecutive measurements: the main unit (e.g., centimeters), subdivisions (e.g., millimeters), and further subdivisions (e.g., fractions of a millimeter), achieved through diagonal lines.
Evaluating options
Step 3: Analyze the options:
- (A) 3: Correct, as diagonal scales show three levels of measurement precision.
- (B) 4: Incorrect, as four levels are not standard.
- (C) 2: Incorrect, as it undercounts the levels.
- (D) 5: Incorrect, as it exceeds typical design.
Thus, the correct answer is (A).
