*HW8_1 The distance a spring stretches from its "free length" is a function of how much tension force is applied to it. The following table gives the spring length, y, that was produced in a F (Ib) particular spring by the given applied force F. The spring's free length is 4.7". Find a functional relation between F and x, the extension from free length (x -y -4.7), with a least-squares fit. The function must pass through the origin (x-0, f-0). The slope of this line is the spring constant, k. Spring length y (in) 4.77.2 10.6 12.9 0 0.471.15.64
