Vernier Calliper Test

What is the function of a Vernier Calliper?

• Measuring temperature accurately

• Weighing objects with high precision

• Measuring internal and external dimensions with high precision

• Calculating angles precisely

How do you read measurements using a Vernier Calliper?

• Read only the main scale

• Ignore the Vernier scale

• Align the object, read the main scale, find the Vernier scale line, and add the two values together.

• Subtract the main scale from the Vernier scale

Name three parts of a Vernier Calliper.

• Main scale, Vernier scale, Jaws

• Pointer, Slider, Depth gauge

What is the main scale on a Vernier Calliper used for?

• Measuring whole units or centimeters

• Measuring time

• Measuring angles

• Measuring weight

Explain the purpose of the Vernier scale on a Vernier Calliper.

• To provide more precise measurements by allowing readings between the main scale divisions.

• To provide a backup scale for comparison

• To adjust the main scale divisions

• To measure temperature accurately

How do you ensure accurate measurements with a Vernier Calliper?

• Close the jaws gently, ensure object is parallel, read measurement at eye level.

• Hold the object at an angle

• Read the measurement from a distance

• Slam the jaws shut forcefully

What is the least count of a Vernier Calliper?

• 0.03 mm

• 0.04 mm

• 0.1 mm

• 0.02 mm or 0.05 mm

Describe the process of measuring the diameter of a small sphere using a Vernier Calliper.

• The process involves placing the sphere between the jaws, reading the main scale value, aligning the Vernier scale, and adding the two readings to get the diameter measurement.

• Estimate the diameter by comparing the sphere to known objects of similar size

• Use a ruler to measure the circumference of the sphere and divide by pi to get the diameter

• Place the sphere on a flat surface and estimate the diameter visually

Why is it important to keep a Vernier Calliper clean and well-maintained?

• Rust build-up, increase weight, decrease precision

• Messy appearance, attract insects, reduce accuracy

• Accurate measurements, prevent damage, extend lifespan

• Inaccurate measurements, cause damage, shorten lifespan

What is the difference between an inside and outside measurement with a Vernier Calliper?

• The difference is in the color of the measurement markings

• An inside measurement is taken with the left hand, while an outside measurement is taken with the right hand

• Inside measurements are always more accurate than outside measurements

• The difference between an inside and outside measurement with a Vernier Calliper is whether the jaws are closed (inside) or open (outside) when taking the measurement.
