20-Sept-2016: Measuring the Density of Metal Cylinders and Propagated Uncertainty in Measurements

Apparatus: Vernier caliper, a aluminum cylinder, and a tin cylinder.


Purpose: To find out the cylinder's density, and calculate the propagated uncertainty

Model: ρ = m/v

Process: We use the vernier caliper to measure the height and diameter of aluminum cylinder and tin cylinder. Then, we weigh the cylinders.

 We get the datas which shows on the white board and calculation is showed on the white board:

Therefore,we get these density of the cylinders and the propagated uncertainty of these density.
