What will be the least count of a Vernier caliper with 20 divisions on the vernier scale and LC of main scale is 1 mm?
0.1mm
A Vernier caliper has 20 divisions on the Vernier scale, which coincide with 19 on the main scale. The least count of the instrument is 0.1mm. .
What is the least count of a Vernier caliper if 19 Main scale divisions 19 mm are divided into 20 equal parts in the vernier scale?
0.1 mm
A vernier callipers has 20 divisions on the vernier scale which coincide with 19 divisions on the main scale. The least count of the instrument is 0.1 mm.
How do you count the number of divisions of the vernier scale?
Solution: In given Vernier calipers, each 1 cm is equally divided into 8 main scale divisions (MSD). Thus, 1 MSD = 1/8 = 0.125 cm. Further, 4 main scale divisions coincide with 5 Vernier scale divisions (VSD) i.e., 4 MSD = 5 VSD.
How do you find the value of the main scale and the vernier scale?
How to Read a Linear Vernier Scale
- Read the main scale. Look for the last whole increment visible before the 0 (zero) mark.
- Read the secondary scale (Vernier) measurement. This is the division tick mark that lines up best with a mark on the main scale.
- Add the two measurements together.
How many scales are there in vernier calipers?
two scales
Any instrument that uses a vernier will have two scales, a main scale and a vernier scale as is seen in Figure 2. A measurement is made by combining the readings from the two scales.
What is the least count of the vernier calliper having 50 divisions in vernier scale?
The least count = 1/50. so precision in measurements = 1/50 × 0.5 mm = 0.01 mm.
How many divisions are on main scale?
On the Vernier caliper, the main (stationary) scale is divided in to millimeters. The Vernier (moveable) scale is 9 mm long and consists of 10 divisions. Each division on the Vernier scale, then, is 0.9 mm long, or 0.1 mm less than the main scale divisions.
What is main scale of vernier caliper?
For the main scale on the common vernier caliper this is probably 0.1 cm. With the vernier scale the least count might be 0.002 cm. The scale on the larger, fixed portion of the caliper. It gives the most significant digits in the reading.
How do you find the main scale reading on a vernier caliper?
The main scale on a Vernier caliper typically tells you the whole number plus the first decimal. Read this just as you would a ruler, measuring to the zero mark on the sliding (Vernier) scale. For example, if the 0 on the sliding scale lines up with the 2 inch mark, your measurement is 2 inches.
How do you find the main scale reading?
The main scale reading is the first reading on the main scale immediately to the left of the zero of the vernier scale (3 mm), while the vernier scale reading is the mark on the vernier scale which exactly coincides with a mark on the main scale (0.7 mm). The reading is therefore 3.7 mm.
