Question

one way that an engineer’s scale differs from an architectural scale is that the engineer’s scale ______

• uses fractional values
• is based on units of 10
• cannot be used to scale long distances
• is only used for drawings of machinery

Explanation:

• Analyze each option:
• "uses fractional values": Architectural scales often use fractional values (e.g., 1/4", 1/8"), while engineer's scales are decimal - based, so this is incorrect.
• "is based on units of 10": Engineer's scales are based on decimal (units of 10) systems (e.g., 1:10, 1:100, 1:1000), unlike architectural scales which are often fractional. This is correct.
• "cannot be used to scale long distances": Engineer's scales can be used for long - distance scaling (e.g., in civil engineering for large - scale projects), so this is incorrect.
• "is only used for drawings of machinery": Engineer's scales are used in various engineering fields (civil, mechanical, etc.) not just machinery, so this is incorrect.

Answer:

B. is based on units of 10
