9/16/2014 Determination of an unknown mass.

Purpose:
Purpose of this lab is to find the unknown mass of our object by using the tension of the strings holding the object up and calcuating the error.

Experiment:
The first thing we did was zero our spring scales to make sure we are getting a good reading. Then we attached the object to both string leaving the object hanging. We measured the angles the wire created on both sides of the poles holding up the object.

Here is a picture of our setup.

Results:
Once we had our measured angles and measurement for tension we calculated our results as shown below.

Then we took our uncertainties as +- for degrees of angle and 0.5 for tension of newtons and measured our propagated uncertainty.

Here is a picture of our calculated results.
