B) metric scale
C) civil engineer's scale
D) full scale
E) half scale

Question 14

On ten of the triangular architect's scales, each inch represents a specific increment of feet. Each of the feet is subdivided into multiples of 12 parts to represent inches and fractions of an inch.

Question 15

If a mechanical drawing shows a scale of 1:4, what does this mean?

A) The drawing was finished on January 4th.
B) The drawing has a four times scale.
C) The drawing has a quarter scale.
D) The drawing has a fourteen scale.
E) none of the above

Question 16

A scale establishes a proportion used in determining the dimensional relationship of an actual object to the representation of the same object on a drawing.

Question 17

The mechanical engineer's 50 scale is for scaling dimensions that require additional accuracy, because each inch has 50 divisions, making each increment .05 in. (1 ¸ 50 = .05)
