The chart below shows a stress strain curve produced by tensile loading. Using an attached copy of the diagram, label the following:- a) Stress (o) axisb) Strain (ɛ) axisc) Elastic region d) Plastic region e) UTSf) Fracture Point g) Yield Stress h) Necking region

What is the equation for Hooke's law and describe the units for each variable. j) On your attached copy, draw a stress strain curve for a brittle material with a higher UTS. Label the UTS and Fracture stress on this curve.(3 marks)
