¿Cuál es un ejemplo de una escala de 1 a 2?

Engineering drawings use scales to represent objects accurately when they are too large or too small to be drawn at actual size.

Based on the LibreTexts excerpt, scales generally fall into three main categories:

1. Full Scale (1:1)

• Meaning: 111 unit on the drawing equals 111 unit in reality.

• Use Case: Used when the object can fit comfortably on the paper at its actual physical size.

2. Reducing Scale (e.g., 1:2, 1:5, 1:100)

• Meaning: The drawing is smaller than the actual object. The first number represents the drawing, and the second number represents reality.

• Examples:

  • 1:2 (Half scale): 1 inch1\text{ inch}1 inch on paper =2 inches= 2\text{ inches}=2 inches in reality.

  • 1:100 (Architectural scale): 1 cm1\text{ cm}1 cm on paper =100 cm= 100\text{ cm}=100 cm (1 meter1\text{ meter}1 meter) in reality, commonly used for floor plans.

3. Enlarging Scale (e.g., 2:1, 5:1, 50:1)

• Meaning: The drawing is larger than the actual object.

• Examples:

  • 2:1 (Double scale): 2 inches2\text{ inches}2 inches on paper =1 inch= 1\text{ inch}=1 inch in reality, making small details easier to see and dimension.

  • 10:1: 10 mm10\text{ mm}10 mm on paper =1 mm= 1\text{ mm}=1 mm in reality, frequently used for tiny mechanical watch parts or micro-components.
