a) Determine state of stress at all points (a, b and c). These points are located on the exteriorsurface of the beam. Point a is located along the centreline of the beam, point b is 15mmfrom the centreline and point c is located on the edge of the beam. Present yourresults in a table and ensure that your sign convention is clearly shownb) Construct Mohrs circle at this point andcalculate the principal stresses and maximum in‐plane shear stress (τmax) at pointc. sketch the resulting state of stress at this point clearly indicating themagnitude of the stresses and any angles associated with the state of stress (principal ormaximum in‐plane shear).
