Scale Drawings

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 paper, maintaining the same ratios as the actual dimensions.

Front

What does the scale '1 to 48' mean?

Back

It means that every 1 unit of measurement on the model represents 48 units of the same measurement in reality.

Front

How do you calculate the actual height of an object from a scale model?

Back

Multiply the height of the model by the scale factor. For example, if the model is 102 mm and the scale is 1:48, the actual height is 102 mm x 48 = 4,896 mm.

Front

What is the formula to find the scale used in a drawing?

Back

The scale can be found by dividing the actual length by the length in the drawing. For example, if the goat pen is 18 m in reality and 6 cm in the drawing, the scale is 18 m / 6 cm = 3 m/cm.

Front

If a map scale shows 3 inches represents 1.25 miles, how do you find how many inches represent 10 miles?

Back

Set up a proportion: 3 inches / 1.25 miles = x inches / 10 miles. Cross-multiply and solve for x to find that 10 miles equals 24 inches.

Front

What does the term 'scale' refer to in a drawing?

Back

The scale indicates the ratio of the drawing's dimensions to the actual dimensions, helping to understand how lengths on the drawing correspond to real-world measurements.

Front

If a drawing shows a road that is 2 inches long and the scale is 1 inch to 5 miles, how many miles is the actual road?

Back

Multiply the length in the drawing by the scale: 2 inches x 5 miles/inch = 10 miles.

Front

True or False: The scale tells us what some length on the scale drawing represents in actual length.

Back

True.

Front

What is the purpose of using scale drawings?

Back

Scale drawings allow for accurate representation of large objects or areas on a smaller, manageable size while preserving proportions.

Front

How do you convert a scale drawing measurement to actual measurement?

Back

Multiply the measurement on the drawing by the scale factor to get the actual measurement.
