shows a steel spring. Describe an experimental procedure for obtaining the results needed to plot an extension–load graph for this spring. In an experiment to obtain results for an extension–load graph, a spring is stretched beyond its limit of proportionality. On , sketch the extension–load graph for this spring. load extension On your graph in , mark and label with a P the limit of proportionality. The limit of proportionality for this spring occurs at a load of 8.5 N. The extension of the spring is equal to 0.014 m when the load is equal to 3.5 N. Calculate the extension for a load of 5.5 N. extension =
