Question 19

Precision instruments for measurements (4)

Answer 19

• Inside and outside calipers
• Micrometre
• Vernier gauge
• Digital vernier caliper

Question 20

Use of inside and outside calipers

Answer 20

• Measure the inside or outside of a material
• inside looks like a compass + chopsticks
• outside looks like a pear

Question 21

Use of micrometre

Answer 21

• Measure depth, length, or thickness to a high density of accuracy
• looks like a horse shoe with a stick
• i think we used in physics before

Question 22

Use of vernier gauge

Answer 22

• Measure internal and external distances with precision and accuracy
• i think we used one before like the ruler but you can slide the thing to fit the object that doesn’t make sense

Question 23

Use of digital vernier caliper

Answer 23

• Measure internal and external distances
• Has an LCD display that can be set to either imperial or metric units
• a digital ver of vernier gauge
