# What is the smallest division on the meter stick scale?

Space and AstronomymillimeterMeter stick. That is, **the millimeter** is the smallest subdivision on the meter stick, which can be seen in Figure 1. This means the millimeter is the unit of the smallest reading that can be made without estimating.

## How do you find the smallest division on a scale?

Video quote: *And the fine lines divide the centimeter into ten equal parts hence the least count of the centimeter scale is one tenth of a centimeter or one millimeter.*

## What are the divisions of a meter stick?

Metersticks are usually divided with **lines for each millimeter (1000 per meter) and numerical markings per centimeter (100 per meter), with numbers either in centi- or millimeter**. Yardsticks are most often marked with a scale in inches, but sometimes also feature marks for foot increments.

## What is the smallest graduation in a Metre rule?

The Metre Rule The metre rule is graduated in centimetres and millimetres. The smallest graduation of the metre rule is **1 mm or 0.1 cm**. This is its reading accuracy. Measurements can be estimated up to half this smallest graduation, i.e. 0.5 mm or 0.05 cm.

## What is the smallest measurement of meters?

Answer: The smallest unit for length measurement in the metric system is **the millimeter**.

## What is the smallest division on the micrometer?

The micrometer thimble is divided into twenty-five equal parts. One complete rotation of the thimble coincides with the smallest division on the sleeve. Thus, the division on the thimble is **one-twenty-fifth of .** **025″** or .

## How do you find the main scale division?

Thus, 1 division on the main scale is equal to **xm1=xm2=1/10=0.1 x m 1 = x m 2 = 1 / 10 = 0.1 cm**. In calipers C_{1}, 10 equal divisions on the Vernier scale are equal to 9 main scale divisions.

## How do you find the smallest division on a vernier scale?

The Vernier caliper is an instrument that allows you measure lengths much more accurate than the metric ruler. The smallest increment in the vernier caliper you will be using is **(1/50)mm = 0.02mm = 0.002cm**.

## What is the value of 1 main scale division?

The main scale is graduated with value of one division on it equal to **1 mm**. The graduations on the vernier scale are such that the length of n divisions on vernier scale is equal to the length of (n – 1) divisions of the main scale.

## How do I calculate least count?

Least count of a Vernier scale is calculated using the following formula, **Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 =** This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.

## What is least count of scale?

The least count of an instrument is **the smallest measurement that can be taken accurately with it**. The least count of meter scale is 1mm, and that of the ammeter shown below is 2 ampere.

## What is LC of Screw gauge?

The least count of screw gauge is **equal to the ratio of pitch of the screw to the number of the division on circular scale**. For example: Pitch of the screw =1 mm. Number of circular scale division =100. ∴ Least count of screw gauge =1001mm=0.

## What is LC of Vernier caliper?

The LC of vernier calliper is **the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm**. The lowest count error is the error correlated with the instrument’s resolution.

## What is the smallest reading of vernier caliper?

The least count of the Vernier caliper is **0.1 mm**. That is, 0.1 mm is the smallest scale reading that can be made without estimation.

## What is the least count LC of the screw gauge?

0.001 mm

The vernier caliper’s minimum count is 0.01 mm while the screw gauge’s minimum count is **0.001 mm**.

## How is screw gauge calculated?

Screw Gauge Formula

**Total Reading = Pitch Scale Reading + Circular Scale Reading x LC of the gauge**.

## How many divisions are there in screw gauge?

The pitch of a screw gauge is 1mm and there are **100 divisions** on its circular scale.

## How the LC of a screw gauge is found?

The formula of least count of screw gauge is as follows: **Least count of screw gauge = (Pitch)/(number of divisions)** Least count of micrometer screw gauge = (1 mm)/(100) = 0.01 mm.

## What is pitch and least count?

**Pitch is often defined as the smallest reading that can be taken from the main scale.** **Least count is the smallest measurement one can do with an instrument.**

## What is LC of spherometer?

The least count of the spherometer is **0.01 mm**.

## What is a zero error class 11?

Zero error is defined as **the condition where a measuring instrument records a reading when no reading is required**. In case of Vernier calipers it occurs when a zero on the main scale does not coincide with a zero on Vernier scale it is called zero error for Vernier.

## What is the use of upper jaws?

The upper jaw holds the top teeth in place and **supports muscles involved in chewing and facial expressions**. It is a major bone in the face.

## What is backlash error?

Backlash error is **the error in the motion which occurs while changing the direction of gears**. If by reversing the direction of rotation of the thimble, the tip of the screw does not start moving in the opposite direction immediately but remains stationary for a part of rotation; it is called backlash error.

## What is the blackish error how do you reduce it?

-Backlash in screw gauges can be avoided by **carefully spinning the screw in one direction**. -Backlash error occurs when the tip of the screw does not start moving immediately after reversing the direction of rotation of the thimble owing to wear and tear of the screw thread.

## How pitch and least count of a screw gauge are related?

The smallest reading up to which a screw gauge can be measured is called least count of screw gauge. It can be find out by following method; **L.C = pitch of screw gauge ⁄ no.** **of divisions on circular scale** i-e 1mm⁄100 = 0.01 mm. The least count error is the error associated with the resolution of the instrument.

## What is the backslash error of the screw gauge means and how do you avoid it during measuring a length?

The reason for this is the wear and tear of threads of screw. To avoid the error, while taking the measurements, **screw should be rotated in one direction only**. If it is required to change the direction of rotation of screw then do not change the direction of rotation at once.
