Scale drawings Before studying this lesson about scale drawings,you should review the lesson about solving proportions.Since it is not always possible to draw on paper the actual size of real-life objects such as the real size of a car or an airplane, we need scale drawings to represent the size like the one you see below of a van. We can also write our scale statement as a fraction, which is the scale factor. SF = Example 2: Write a scale statement for the reduced or enlarged object, and calculate the scale factor used to create the reduced or enlarged object.

Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph. Original Scale Diagram. Scale factor = length on scale diagram = 9 = 3 length on original diagram 3. Note the units must be the sameon the original and scale diagram if not, you must convert one to make them the same scale factors do not have units. Example # 2.
