1. merits of the metric and the British systems for use with micrometers.
2. in a micrometer. there are 40 smallest divisions on the main scale per inch. one complete turn of the circular scale makes the one smallest division on the main scale and there are 25 divisions on the circular scale. what is the reading in inch of one division on the circular scale? in mm?
3. a scale whose smallest divisions are in centimeters is to be provided with vernier which will enable fifths-of-centimeter divisions to be accurately estimated. how many vernier divisions should be used, and how long will each one be?
4. sketch a linear vernier that has a ratio 5:4 vernier to scale that will divide quarter inch into fifths and make a sketch to read 1:15 inch.
