Scale Drawing and Models

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or area that is proportionally reduced or enlarged to fit on a smaller or larger surface, using a specific ratio or scale.

How do you calculate actual distance using a scale?

Back

To find the actual distance, multiply the distance on the scale drawing by the scale factor. For example, if the scale is 0.5 inch = 15 miles, and the distance on the drawing is 2 inches, the actual distance is 2 inches * (15 miles / 0.5 inches) = 60 miles.

What does the scale 1 inch = 120 feet mean?

Back

This means that every 1 inch on the drawing represents 120 feet in reality.

If a map shows two cities 2.5 inches apart, how do you find the actual distance between them using a scale?

Back

Multiply the distance on the map (2.5 inches) by the scale factor. If the scale is 0.5 inch = 15 miles, then the actual distance is 2.5 inches * (15 miles / 0.5 inches) = 75 miles.

Front

What is the formula to convert scale measurements to actual measurements?

Back

Actual Measurement = Scale Measurement * (Actual Distance / Scale Distance).

Front

How do you find the actual length of an object from a blueprint?

Back

Multiply the length on the blueprint by the scale factor. For example, if the blueprint shows 9.1 inches and the scale is 1 inch = 120 feet, the actual length is 9.1 inches * 120 feet/inch = 1092 feet.

What is the significance of scale in architectural drawings?

Back

Scale is crucial in architectural drawings as it allows designers to represent large structures accurately on a manageable size paper, ensuring that proportions are maintained.

Front

If lamp posts are 2.5 inches apart on a plan with a scale of 0.5 inch = 9 yards, what is the actual distance between them?

Back

The actual distance is calculated as 2.5 inches * (9 yards / 0.5 inches) = 45 yards.

Front

What does it mean if a garden is represented as 14 cm by 10 cm on a scale of 1.6 cm = 2 m?

Back

It means that the actual dimensions of the garden are found by multiplying the scale dimensions by the scale factor. The actual dimensions are 14 cm * (2 m / 1.6 cm) = 17.5 m and 10 cm * (2 m / 1.6 cm) = 12.5 m.

Front

How do you determine the scale of a drawing if you know the actual distance?

Back

To find the scale, divide the actual distance by the distance on the drawing. For example, if the actual distance is 90 feet and the drawing shows 2.5 inches, the scale is 90 feet / 2.5 inches = 36 feet per inch.
