A vernier calliper has 20 divisions on the vernier scale one centimeter on main scale is divided into 20equal parts Find the least count of vernier parts?
0.1 mm
What does the smallest division on the main scale of the vernier caliper correspond to?
1mm
How do you calculate readings of sextant?
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
What is Least count of vernier calliper and micrometer gauge?
LC FOR VERNIER CALIPER-0.1mm LC FOR MICROMETER -0.01 mm L.C- NO OF SMALLEST DIVISION ON MAIN SCALE ------------------------------------------------------- TOTAL NO OF DIVISION ON VERNIER SCALE
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
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.
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.
Where on the vernier caliper would you read to obtain the main scale reading?
The main scale is before the zero line of the vernier scale.
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 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.

0.1 mm
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.
Define the term zero error of vernier calliper?
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.
What is the least count of screw gauge and vernier calipers?
LC FOR VERNIER CALIPER-0.1mm LC FOR MICROMETER -0.01 mm L.C- NO OF SMALLEST DIVISION ON MAIN SCALE ------------------------------------------------------- TOTAL NO OF DIVISION ON VERNIER SCALE
What is the least count value of vernier caliper and screw?
LC FOR VERNIER CALIPER-0.1mm LC FOR MICROMETER -0.01 mm L.C- NO OF SMALLEST DIVISION ON MAIN SCALE ------------------------------------------------------- TOTAL NO OF DIVISION ON VERNIER SCALE
How does the zero error occur in the vernier calipers?
It occurs when the '0' marking of the main scale is not in line with the '0' marking of the vernier scale when the jaws are fully closed.
