EXAMPLE 4.1.6Spring Constant of a Lever SystemProblem Figure 4.1.11 shows a horizontal force f acting on a lever that is attached to two springs. Assume that the resulting motion is small enough to be only horizontal and determine the expression for the equivalent spring constant that relates the applied force f to the resulting displacement x.194CHAPTER 4: Spring and Damper Elements in Mechanical SystemsFigure 4.1.11: A lever-spring system.kxR (c)(a)(b)

SOLVED:When different loads hang on a spring, the spring stretches to different lengths as shown in the following table. (a) Make a graph of the applied force versus the extension of the spring. By least-squares fitting, determine the straight line that best fits the data. Do you want to use all the data points, or should you ignore some of them? Explain. (b) From the slope of the best-fit line, find the spring constant k. (c) The spring is extended to 105  mm. What force does it exert on the su
