Before you go ahead with this text reading and to interact with the simulator, perhaps you may prefer to review the process to the reading, interpretation and use of the fractional inch without use of the thta is the pre requisite to its comprehension. We recomend also to check this topic: vernier scale: simulator of reading and interpretation in fractional inch resolution 1/128" .
We saw in the topic: Use of measures in fractional inch - comprehending and measuring without that to read one ruler or line gauge with main scale in fractional inch it is not a mistery that most people imagine.
In the topic vernier scale: simulator of reading and interpretation in fractional inch resolution 1/128" we saw how each division of the main scale represents 1/16 (one sixteen avos) of inch. We saw also that this space is divided by the vernier by eight and that the value of the measure is obtained by the sum of the integer, the fraction of the main scale is the fraction of the nonius. With the improvement brought by the practice, this sum becames automatic. However, or oito and that the measurement value is obtained by adding the whole, the fraction of the main scale and the fraction of vernier. With the improvement brought by the practice, this algebra becomes automatic. all in all, not always have time to perfect this whole thing.
I am gonna give you some tips.
We saw in the topic: Virtual inch vernier caliper - simulator in 1/128" fractional - metrology that the engeneering of the use of teh vernier is in how to identfy in which part of the distance between two marks (of 1/16") the zero of the vernier is. For example: when the zero in the vernier is in the middle of the distance between ine mark and another, for example, we sum half of 1/16" (1/16 * 1/2 = 1/32) to the measure of the main scale. The number 4 (that is half of 8) of the vernier aligned indicates this (if you didn;t understand anything is a signal that you must interact with the page above and later come back here)
In the image beside, the fifth mark of the vernier indicate that we must sum 5/128 to the measure of the main scale.
We saw an easy way to create this reasoning thta is:
This algebra can, in the beggining, let someone bothered and afraid to make counts. There is a way even more simple to read these measures:
Each mark of the main scale is equal to 8/128" (1/16 = 2/32 = 4/64 = 8/128 - see in the vernier one number 8 to help to to remember) so:
With the experience, go observing if the mark of the vernier that aligned is a pair number that we can simplify before starting the calculations, in order to facilitate even more the counts. Let's supose that the fourth mark of the vernier was aligned in the previous figure, (we can infer that the result will be equal to the measure that we calculate minus 1/128) but let's make it reading and interpretating it. Let's go:
The figure 2 of the topic: vernier scale: simulator of reading and interpretation in fractional inch resolution 1/128" demystifies the fraction and, in special, the denominator that the vernier shows.
The tip is: if the denominator is:
It is also good if you memorize this list.
