main scale is the least accurate reading on the device. the vernier scale uses an offset of divions that only allows one "line" or division to line up with the scale below. This scale is more accurate than the main scale. for example, the main scale may produce an accuracy of 0.125 of and inch plus or minus 0.125 of an inch, whereas the vernier would produce an accuracy of 0.025 of and inch. therefore if two divivions of the main scale and one division of the vernier scale were combined it would prodice and reading of (0.125+0.125+0.025 = 0.275) inches.
What is a thimble on a vernier scale?
the modified mercalli scale was VII-VIII
There are 2 ways.Richter scale. This is an objective method, and is a scale of 1-10, each 0.1 increase in size is a 10 fold increase in power. (it is only possible, even with a mega-thrust quake to reach 9 on the Richter scale). This is the most accurate and commonly used scaleMercalli Scale. This is a subjective scale, and the reading is based on the damage done by the earthquake. It is a scale of roman numerals between 1-14.
The metric temperature scale is called the Celsius scale. The scale divides the range of temperatures between freezing and boiling at standard atmospheric condition into 100 equal parts.
Concerning that the highest reading is 7, so a 6.3 Richter can cause very big damage
where on the vernier caliper would you read to obtain the vernier scale reading
No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
Vernier scale consists of main scale and vernier scale. The first line or the zeroth line coinciding with the main scale reading is the main scale reading. The vernier line except zeroth line coinciding with any line on main scale is the main scale reading.
We need two readings. One is Main scale reading and the other is vernier scale reading. Main scale reading will be read on the main scale. We need an indicator to read it. Right? The marking ie zero of the vernier is that indicator. So the reading on the main scale which has been just crossed by zero of the vernier is taken as Main scale reading. Now to get VSR, we need vernier scale coincidence. How do we get this? Any one of the divisions of the vernier will be found coincided with some divisions marked on the main scale. We don't worry about that main scale division but we concentrate only on the vernier scale division. This is VSC This VSC is to be multiplied by least count. So VSC x LC gives the VSR Now MSR + VSR gives the accurate reading.
It can, but the vernier is capable of a more accurate reading.
Find the marks that line up exactly (or as exactly as possible and then interpolate). see the Sources and related links below for a page and a video explaining in detail.
To obtain the main scale reading on a vernier caliper, you would read the measurement value aligned with the zero mark on the main scale.
First we keep the body in between the jaws of the caliper. Then we note the main scale reading and then vernier coincidence. Vernier coincidence is to be multiplied by the least count of the device. This is added with the main scale. That will be the required value of the dimensions of the object.
let us think with all our common sense.The indicator which reads the reading on the main scale is the zero mark on the vernier.On the main scale each mm is divided into half mm. Hence the reading would be read for divisions on the main scale. ie say I start from 3 cm.3 cm, 3.05 cm, 3.1 cm, 3.15 cm, 3.2 cm, 3.25 cm and so on.But for our convenience let us read as 3.000 cm, 3.050 cm, 3.100 cm, 3.150 cm, 3.200 cm, 3.250 cm and so on,Now say your indicator ie zero marking on the vernier is lying in between say 3.200 and 3.250 cm. Then main scale reading would be recorded by taking the lower value namely 3.200 cm.Now the vernier would give the last two decimal values for accuracy. If the 43rd division on the vernier get coincided with some line on the main scale, then the vernier reading will be got by multiplying this vernier coincidence 43 by the least count. The least count will usually be 0.001 cm.So the vernier scale reading will be 0.043 cmNow by adding this along with the main scale reading ie 3.200 cm we get 3.243 cm.Another example: If suppose the indicator lies in between 6.450 and 6.500. The vernier division 17 get coincided.Main scale reading is 6.450 cmVernier scale reading is 0.17 cmSo the total reading ie accurate reading is 6.467 cmUNNATI CHANDANESTD:XII
vernier calliper scale. give us reading upto two places right side from decimal
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
