Q1 Note: all figure dimensions in mm and 3rd angle projection unless noted. g=10ms² unless noted. Using diagrams indicate the principal constituents of the surface of a metal 4 marks component (for example a steel bolt) as would be seen by taking a cross section of the component at right angles to its surface. Outline the concept of surface integrity, writing notes on its two principal 4 marks characteristics, and describe surface defects that are likely to be encountered when studying the surfaces of various metallic components. Using a diagram, indicate the principal characteristics of surface roughness, taking 4 marks account of error of form, waviness and roughness. Using a schematic diagram, indicate the general principle behind the (a) physical 8 marks measurement of and (b) the reporting of surface roughness.
