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.

Instrument used to measure the diameter of a marble.

If you know the radius of a circle you multiply it by 2 to get the diameter. 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. The measurement is shown in the figure 2. 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.

My idea is that with this system the largest size of the marble is measured. R3 3 volume of sphere. We used this instrument in a physics lab to measure the diameter of a tennis ball marble etc. As a marble is a sphere and a sphere is an endless number of circles it is impossible to squeeze a circle with a diameter of 2 1 2 inch through a 2 7 16 inch hole.

Write down the measurement. If you know the circumference of a circle you divide by pi to get the diameter you measure it. You use a triple beam scale to measure mass. 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.

Measure the perimeter of the wheel using a tape measure. Most templates measure to 16ths of an inch. I have seen cards boards with different size holes in it to use for measuring the size of marbles.
