Term 1 Week 7

This week, we played around with two main things-the vernier caliper and micrometer screw gauge.

Such complicated names.........

Scared me at first.

Lucky, they are just two other measuring instruments. The normal meter ruler can measure up to 0.1cm. The vernier caliper can measure up to 0.01 cm. The micrometer screw gauge can measure up to 0.001 cm (or 0.01 mm)




...so much more elaborate than a ruler. Both of them take quite a long process to measure when you compare with a ruler...

(I'm too lazy to explain the whole thing so here's a video on how both work)



I was wondering how to measure huge objects yet with great precision. Especially for things like rockets that require extraordinary precision. Do they have a giant vernier caliper...
