Question 2 The stress acting on two planes at a point is indicated in Fig. 2. Determine using the stress transformation equations: a) the shear stress on plane a- a and sketch the orientation of the element with the relevant stress components. b) the principal stresses at the point (sketch of orientation of the element in principal direction not required). Hint: Associate plane b - b with the x - y and plane a - a with the x'-y' coordinate system. b [MPa] 80 Ta 90°
