(Solved): this is all apart of 1 question, please answer in neat and in detail. Dont answer in short thank you ...

- Describe the relationship between stress, strain and Young's Modulus. Propose descriptions in graphical form if you desire. - Sketch the effects of 2D and 3D tensile loading on a titanium workpiece shown below : A loaded steel thin-walled circular cross-section has an external diameter of \( 80 \mathrm{~mm} \), internal diameter of \( 72.5 \mathrm{~mm} \), Length of \( 25 \mathrm{~m} \), a Young's Modulus of \( 200 \mathrm{GN} / \mathrm{m}^{2} \), Poisson's Ratio of \( 0.29 \). If the supply pressure is 65bars calculate; a) The Hoop and Longitudinal stresses b) The Hoop and Longitudinal strains c) The increase in diameter due to the hoop strain d) The increase in length due to the longitudinal strain e) The volumetric strain - Assess the effects of volumetric thermal expansion and contraction Analyse the behaviour of the above workpiece if it was subjected to both a tensile load and a bending moment
