») Figure Q3(b) shows a concrete corbel structure, fixed rigidly to a wall support. It is subjected to a point load 400 kN at a distance 0.5 m from the support. The depth of the corbel section is 300 mm, and the moment of inertia Ix is 4.5 x 108 mmª. (i) 400 KN 0.5m Neutral axis B₂ A₂D FIGURE Q3(b) T 300 mm Calculate the bending moment and shear force in the beam at the support. Then calculate the normal and shear stresses acting on the element A' and B'. (ii) Determine the values and directions of the principal stresses for the element A' and B', using either basic equilibrium principle or Mohr's circle diagram.
