What is the spring constant K for the double spring, in Nfcrn, and in Wm ?. Explain how you determine K from the graph. [6 pts} Eastic force us Compression - You just discovered that a double spring behaves like a single spring but with a larger spring constant. Theoretically, we expect that the elastic constant of a double spring made of identical springs is twice the elastic constant of each spring. Is this true for your results? How far is your result, percentagewise, from the theoretical expectation? What do you think is the reason{s} for the difference? {4 pts} Overview In this experiment you will study the elastic force of a single and a double spring. You will take measurements of the elastic force, compare it to Hooke's Law prediction and determine the spring constants. Hooke's Law states that the elastic force opposes the deformation and is proportional to the deformation of an elastic object: Fel = kx Here x is the deformation and could be either stretch or compression, and k is the elastic constant. The unit for k is N/m if the force is measured in Newtons and the deformation in meters. You will check the validity of this law first for a single spring and then by a double spring. In each case you measure the elastic force For for various deformations x, and then analyze the graph Fez vs x. If Hooke's Law is valid, the best fit to the graph should be a straight line. Furthermore, the slope of the trendline gives an experimental determination of the elastic constant of the object
