The rigid beam shown in Fig. 4-19a is fixed to the top of the three posts made of A-36 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 T = 80°C. -300 mm--300 mm- 150KN/m 60 mm- 250 mm -40 mm 40 mm- SOLUTION Steel Aluminum Steel

The rigid beam shown in Fig. 4-19a is fixed to the top of the three
posts made of A-36 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 T, = 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.
