To quickly assess the difficulty of the text, read a short excerpt:
This is usually ruled horizontally and vertically with 10 or 20 divisions per square inch. The number of full squares enclosed by the figure is counted and with a little care and practice the remaining fractional squares can be closely approximated. (c) Weighing of Areas. After the figure has been traced upon heavy cardboard or thin sheet metal of uniform thickness its outhne is cut. The figure is then weighed and its weight compared to the weight of similar material of known area. {d) Mean Ord...inate Rule. The area of the irregular, Fig. 78, is equivalent to a rectangle, whose base is AB Fig. 78. — Area by Mean Ordinate Rule. which is also the length of the figure, and whose altitude CD is the mean of all the ordinates, i.e., perpendiculars 214 PRACTICAL MATHEMATICS drawn to AB within the figure. The mean of the ordinates extending above AB is CB whereas the mean of the ordinates extending below AB is BD. The product of the mean ordinate CD of the whole figure multiplied by its length AB is the area of the figure.
