The rigid beam shown is fixed to the top of the three posts made of steel and aluminum. The posts each have a length of 250 mm when no load is applied to the beam, and the temper Determine the force (in KN) supported by the steel post if the bar is subjected to a uniform distributed load of 150 kN/m and the temperature is raised to 55°C. Assume vertical upward positive. Material Aluminum Steel Length (mm) 250 250 Diameter (mm) 60 40 Modulus of Elasticity (GPa) 73.1 200 300 mm 300 mm a (/°C) 12x10-6 23x10-6
