a. The data included in the table are from the strain gauges of a hole-
drilling rosette gauge. Calculate the principal stresses using the
incremental hole-drilling technique. The ultra high-strength steel being
analysed has Young's modulus 195 GPa and Poisson's ratio 0.29. The
values for a and b can be used from Activity 19.2b.
In order to achieve full marks, each step of the calculations should be
detailed, including any assumptions being made. Include equations,
screenshots of Excel and written descriptions in your answer, and
graphical representation of data as appropriate.
(20 marks)
b. Describe another residual stress technique that could be used to
characterise the surface stresses at the same depths as in
Question 3(a).

Activity 19.2b: Working through a data set
Now take the data set from the other side of the bent beam. You can
find this in the Activity_19_2b_concave_side_hole_drilling.xlsx file on
the Week 19 resources page. Work through the analysis steps. If you
have already done this for the first side of the beam, you can simply
copy the new strains into the workbook.
