Question 1. What does the slope of the plot of tension
force vs. position represent?
Question 2. For the second run, do you notice nonlinear
behavior at high tension forces? Does this indicate the material is
becoming stiffer or slinkier?
Question 3. What does the trend in the graph indicate
will happen if you keep adding even more tension to the
wire?
Question 4. For a wire that has twice the radius of our
wire, how much would it stretch...
