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.

Multiply the measurement between H and T by 500 Scale: Is a comparison between the actual size of an object and the size of it's diagram.It can be represented as a ratio, fraction, percent, in words or in a diagram. For Example: the scale 1:32 means that 1 cm in the diagram represents 32 cm in the actual obj 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. 4.2 Scale Diagrams Car manufacturers create scale drawings that show what a new car will look like. An actual car measures 339.2 cm in length and 163.2 cm in height. It is drawn to a scale of 1 : 32. Is the drawing an accurate representation of the actual model?
