Question

for drawing the components of a wrist watch, the scale used is ​

Answer 1

Explanation: An engineer's scale is the representation of the scale used in drawing on the drawing sheet numerically. For example, if the length of the drawing is 5 cm and the actual length is 10m, then it is numerically represented as 5cm = 10m.

Answer 2

Enlarging scale is used for drawing the components of a wrist watch.

To properly understand the answer, we have to know more about enlarging scale.

Enlarging scale :

• In enlarging scale drawings, the actual dimesion is smaller than the dimension used in the drawing.
• Which means, if R.F. of a enlarging scale is x:y , then x should be greater than y
• Enlarging scale is basically used to draw extremely small objects or small machine parts.

Now, components of a wrist watch are extremely small and it will be very difficult to draw even in same size scale (actual dimension = drawing dimension).

That's why, the small components are drawn using enlarging scale, for the sake of convenience.

Hence, it is found that the internal components of a wrist watch is drawn using enlarging scale and the reason behind the usage of enlarging scale has also been discussed.
