What reading level is Elements of Physical Manipulation volume 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
To get the whole number of milli- metres, a needle may be laid down on the scale, and the right division distinguished by its point.
If greater accuracy is desired, use the third microscope, find- 56 DIVIDING ENGINE.
ing the magnitude of the divisions of its scale in the following manner; focus it on the steel scale, placing it so that two divi- sions of the latter shall be in the field at the same time. Read each of them by the scale in the eye-piece, and take the differ- ence ; the reciprocal... is the magnitude of one division in millimetres. Repeat a number of times and take the mean. To make any measurement, place this microscope with one of the others over the points to be determined, and take the reading with its scale, esti- mating tenths of a division ; then substitute the steel scale as be- fore, and read the millimetre mark preceding, also that following. By a simple interpolation the distance is obtained from these three readings with great accuracy.
Try both these methods with the objects to be measured, and then test the scale of tenths of an inch by measuring the distance of each inch mark from the zero, and reducing the millimetres to inches.
