- outline the significant differences between rockwell and brinell hardness testWith what is Stress associated and how?1- With the Vickers hardness test a 10 kg load gave for a sample of brass an indentation with diagonals having mean lengths of 0.510 mm. What is the hardness? Again, what is tensile strength of brass? 2- When a load is applied to a brass specimen in a Brinell test, an indentation of 4.10 mm is Ahimary produced. Estimate the tensile strength of the brass.
- 3000 kg, 10mm Steel Ball Brinell Hardness Reading of 421 is equal to what Rockwell C Reading?why specific rigidity is needed?(one option or more can be true, please select from below) Ductile failure is characterised by: Little or no elongation to failure Cavity coalescence Dimples in the fracture surface A significant reduction in cross sectional area The component breaking into many pieces
- What is the relationship factor between the fatigue test and any other mechanical property (tensile test, hardness test, impact test)?(one or more option can be true please select from below) which of the following will reduce the failure strength or lifetime of a test piece and why? Decreasing the grain size, more grain boundaries to initiate failure Raising the temperature above the BDTT, more plastic deformation in the lattice will cause it to fail faster Increasing its volume, greater likelihood of critical defects Decreasing the loading frequency, the material will be at peak stress values for longer Increasing the difference between the maximum and minimum stress values, as this affects the stress concentration factorDescribe the fatigue tests by drawing all the necessary figures.
