In which of the following scales can distance be measured more precisely, assuming the same Representative Fraction (R.F.)?

Correct option is D

The Diagonal Scale allows for more precise measurement compared to the other types of scales listed. This scale provides finer subdivisions for measurement, making it possible to measure smaller units with higher accuracy. Diagonal scales are commonly used in engineering and drafting to measure dimensions accurately up to the second decimal place of a unit.
Information Booster:
The Diagonal Scale is a special type of scale designed to measure distances more precisely by subdividing smaller units accurately. Here's why it stands out for precise measurements:
1. High Precision: The diagonal scale provides a method for measuring distances up to two decimal places of a primary unit. It uses the principle of diagonal lines to subdivide a short distance into finer measurements.
2. Structure: It consists of vertical and horizontal lines. The primary unit is divided into smaller parts on the horizontal line, while the vertical and diagonal lines enable measurements of even smaller fractions within those units.
Additional Knowledge:
· Plain Scale: Suitable for less precise applications, often found in basic maps and diagrams.
· Time Scale: Important in applications like time-motion studies or machinery with periodic functions.
· Revolution Scale: Essential for measuring rotational movements or cycles, especially in turbines and engines.
