What are the main scale and vernier scale readings?
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.
What is the unit of vernier scale reading of vernier caliper?
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
How do you take reading in travelling microscope by using the vernier scale reading from 0.6 to 1.0?
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.
How do you read vernier calipers?
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.
Where on the vernier caliper would you read to obtain the main scale reading?
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.
Differentiate between main scale reading and vernier scale reading?
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 main scale and vernier scale?
1)Main Scale is fixed(It does not move) Vernier scale slides along main scale.2)Least count of Mainscale is 0.1cmLeast count of vernier scale is 0.01cm
What do you understand by zero error of a measuring instrument?
It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.
How do you take reading in traveling microscope?
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
How do you use vanier caliper?
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.
How do you find radius of cylinder when the main scale reading is 35 division and 4 division of vernier scale coincides with a main scale division?
it sounds like the reading is 35.4 millimetres. all you have to do to find the radius is halve it. 35.4 / 2 = 17.7 millimetres
