The load-extension graph of an elastic material is illustrated below. Use the graph to determine the work done in stretching the material
Explanation
Determination of work done from the graph: Work done is the area under the graph
Area = \(\frac{1}{2}\) b * h = \(\frac{1}{2} * 10^{-2} * 4\) = 2 * \(10^{-2}\)
