Question
Mechanical properties of materials • H.W.: • The following data where obtained during the tensile test of mild steel circular bar 12.75 mm diameter and 203.2 mm gauge length. Determine the following: 1) The apparent stress at each point 2) Strain at each point 3) True stress at each point (Assume D at failure is 8,51 mm and D at max. load is 11.15 mm) 4) Draw stress - strain curved based on: a) Original cross sectional area b) True cross sectional area 5) Proportional limit Mechanical properties of materials 6) Modulus of elasticity 7) Upper and lower yield point 8) Ultimate strength 9) Breaking strength based on the original cross sectional area and on true cross sectional area 10) Percentage of elongation 11) Percentage of reduction in cross sectional area. 12) Ductility, Resilience and toughness Load (N) 4393 16902 29357 33360 33627 35584 41366 48839 52709 55378 56356 43768 Deformation 0.0254 0.127 0.228 0.305 0.356 3.81 6.35 11.68 16.76 26.92 43768 42.42 (mm )
