Part A - Question 3 (Total Marks for Part A - Question 3:20) A steel beam in an industrial structure is part of a complicated frame that was difficult to analyse. Using a rectangular strain gauge rosette, the actual strains at point A have been recorded while being subjected to test loads. It is necessary to determine the normal stresses and shear stresses in the actual beam subject to the test loads to check whether the stresses assumed in the...
An existing steel beam is in use in a building. Using a rectangular strain gauge rosette, the actual strains at point A have been recorded while being subjected to test loads which simulate crowd loading. It is necessary to calculate the principal stresses to check whether the beam is safe for its current purpose (ie: assess whether the stresses determined are less than the maximum permissible stresses) Figure 4: Strain gauge rosette location and recorded strains In this case it is reasonable...

I have couple questions for this Problem;
1- can you show me on the graph how to solve and identify the
point using the graph (-5,40)?
2- I solve the question using the equation method and it gave me
correct number the angle was positive 45! shouldn't be -45?

9) Application of stress transformation. Determine normal stress due to P and shear stress due to T. Understand the subscripts of these stress components. Apply the transformation equations to get the normal and shear stress on the weld (need figure out the angle first).
