Chapter 7, Problem 27(choose chapter or problem)
When different loads hang on a spring, the springstretches to different lengths as shown in the followingtable. (a) Make a graph of the applied force versusthe extension of the spring. (b) By least-squares fitting,determine the straight line that best fits the data.(c) To complete part (b), do you want to use all thedata points, or should you ignore some of them?Explain. (d) From the slope of the best-fit line, findthe spring constant k. (e) If the spring is extended to105 mm, what force does it exert on the suspendedobject?F (N) 2.0 4.0 6.0 8.0 10 12 14 16 18 20 22L (mm) 15 32 49 64 79 98 112 126 149 175 190
