Answers
Answer:
vernier caliper is an amazing instrument used for measuring lengths. The reading on a vernier caliper is more accurate than a normal ruler. This instrument can be used to measure depth, inner radius and outer radius of objects. The vernier calipers have two scales, one is the vernier scale and the other one is the main scale The main scale is graduated in centimeters and looks similar to the normal ruler. The vernier scale has 10 divisions, which helps in more accurate measurement.
What is the principle of vernier caliper? The vernier caliper uses the principle of alignment of line segments to determine the more accurate reading. The length of the object to be measured is placed in between the two jaws of the vernier calipers. Certain graduation on the vernier scale gets signed with a reading on the main scale. The decimal value of the measurement is obtained by adding vernier caliper value to the main scale.
