Question 2 - Stress Transformation The state of stress at a point A on the surface of a beam is shown below, assuming the x - y coordinate system shown. A L The stresses point in the directions as indicated above, and have magnitudes given by: • %a = 25 MPa • Ob = 220 MPa T = 190 MPa y b) Find the in-plane principal stresses (assume 'maximum' refers to the most positive value): Omax = MPa Omin = MPa X Part One: Principal Stresses a) Find the in-plane principal angle at the point A on the surface of the pressure vessel, measured relative to the positive x-axis: Op degrees % Part Two: Mohr's Circle An example sketch of Mohr's circle for the state of stress is shown below. It is not drawn to scale, and it is recommended you draw your own Mohr's circle to perform the following calculations.
