A pillar has a uniform section as indicated. It has a length 0.9 m, cross-sectional area 12.2 x 104 m² and second moment of area 1.6 x 10-6 m4. A constraint is applied at a point e = 3 mm away from the neutral axis as shown. The pillar is built-in at the other end. It is made of Aluminium with a coefficient of thermal expansion of 12 x 10-6/°C and a Young's modulus of 70x10⁹ Pa. The pillar experiences an increase of temperature of 39° C. Calculate the stress that will occur on the right-hand face of the beam due to the effect of bending and thermal effects. The distance from the neutral axis to the right- hand face is 60 mm. Give your answer as a positive value in MPa to two decimal places.
