a) A tensile test can be used to generate a stress-strain curve and to determine a variety of material properties. List four properties that can be deduced from a stress strain- curve. [4 marks] b) Describe how you would measure the strain of a material or component being exposed to complex loading system. What considerations would you need to take to ensure accurate measurements were obtained? c) State the limitations of a uni-axial strain gauge. [5 marks] [2 marks] d) A structure is subjected to the compressive stresses shown in the figure below. Draw the Mohr Circle and use this approach to determine: 100 N/mm 100 N/mm' i) ii) 111) The value of maximum direct stress present in the block The value of minimum direct stress present in the block The value of maximum shear stress present in the block [14 Marks] a) A tensile test can be used to generate a stress-strain curve and to determine a variety of material properties.
