I have seen cards boards with different size holes in it to use for measuring the size of marbles.
Instrument used to measure the diameter of a marble.
A balanced scale which compares the mass of one object with that of a known quantity.
Write down the measurement.
Now let us use this vernier calipers to measure the diameter d of a marble ball marble balls usually have d 1 2 in.
Here x m0 is the distance between the jaw attached to main scale left jaw and the 0 th mark on the main scale and x v0 is the distance between the jaw attached to vernier scale.
What is an instrument that measures mass.
Measure the perimeter of the wheel using a tape measure.
We used this instrument in a physics lab to measure the diameter of a tennis ball marble etc.
My idea is that with this system the largest size of the marble is measured.
The measurement is shown in the figure 2.
If you know the circumference of a circle you divide by pi to get the diameter you measure it.
Lay a marble template on the tissue and try the marble in the different holes until you find the one closest to the size of the marble.
Then use the formula to find out the diameter d perimeter 3 14 you could certainly do it that way.
If you know the radius of a circle you multiply it by 2 to get the diameter.
If you can t do that then somehow measure the diameter of the marble divide it by 2 to find the radius and plug it into this formula.
Most templates measure to 16ths of an inch.
