To measure the diameter of a thin wire, there is an 80cm wire, a pencil and a millimeter scale. Design the measurement scheme and write the results
Tightly wrapped around the pencil
How to measure the diameter of a thin wire with a millimeter scale
Take a rope around the wire
Then count the number of turns
The perimeter of the wire can be known by measuring the length of the rope
Then we can find the diameter
How to measure the diameter of wire
Weigh the mass and calculate the volume according to the density. The length of the measuring point will calculate the diameter. I don't know if I use tools
