= The rigid beam shown in Fig. 4–18a is fixed to the top of the three posts made of A992 steel and 2014-T6 aluminum. The posts each have a length of 250 mm when no load is applied to the beam, and the temperature is T1 = 20°C. Determine the force supported by each post if the bar is subjected to a uniform distributed load of 150 kN/m and the temperature is raised to T2 80°C. - 300 mm +-300 mm 150 kN/m 60 mm 250 mm --40 mm 40 mm Steel Aluminum Steel
