Vernier Callipers
Q1: What is a Vernier Calliper?
A vernier Calliper is a measuring instrument used to measure the dimensions of an object with high precision. It consists of a main scale and a sliding vernier scale, which allows for more accurate measurements than a regular ruler.
Q2: How does a Vernier Calliper Work?
A vernier Calliper works on the principle of Vernier scale, which provides finer measurement readings. The main scale measures whole units, while the vernier scale slides along the main scale and provides additional fractional readings.
Q3: What are Parts of a Vernier Calliper?
A vernier Calliper consists of several parts: the main scale, vernier scale, jaws for measuring outer dimensions, and depth gauge for measuring depths. It also includes a locking screw to hold measurements in place.
Q4: How to Read Measurements on a Vernier Calliper?
To read measurements on a vernier Calliper, align the object between the jaws and read the main scale reading at the zero mark of the vernier scale. Then, identify the graduation line on the vernier scale that perfectly aligns with a graduation line on the main scale. The value indicated by the aligned lines on the vernier scale represents the fractional part of the measurement.
Q5: What are Applications of Vernier Callipers?
Vernier Callipers are used in various fields, including engineering, manufacturing, and science, where precise measurements are required. They are commonly used for measuring dimensions of objects, thickness, inner and outer diameters, as well as depth measurements.
Q6: How Accurate are Vernier Callipers?
Vernier Callipers are known for their high accuracy. Depending on the quality and design, vernier Callipers can typically measure to the nearest 0.02 mm or even finer.
Q7: What is the function of the vernier calliper?
Vernier calipers accurately measure internal and external dimensions with a minimal reading error of 0.05mm (0.0019 inches), making them superior to flat devices like rulers.
Vernier Calliper
Vernier Calliper is a precision measuring instrument used to measure the internal and external dimensions of an object. It consists of two main parts:
- A Fixed Jaw
- A Movable Jaw
The fixed jaw is used to measure the outside of an object, while the movable jaw is used to measure the inside of an object. This is a device that is used to measure very smaller values and it can measure the value in the range of 0.1 mm.
