The load-extension graph of an elastic material is illustrated above. Use the graph to determine the work done in stretching the material
Attached Figure / Diagram
Verified Correct Answer: .
Physical Principles & Numerical Solution
Determination of work done from the graph: Work done is the area under the graph
Area = \(\frac{1}{2}\) b * h = \(\frac{1}{2} \times 10^{-2} \times 4\) = \(2 \times10^{-2}\)J
