The rigid beam shown is fixed to the top with the three (3) posts made of Steel and Aluminum. The post has the length as shown when no load is applied to the beam and the initial temperature is 20°C. Consider the material properties below: E (GPa) Steel 200 Aluminum 70 If the final temperature would increase to 60°C, determine the force supported by each post if the bar is subjected to a uniform distributed load as shown. 250 kN/m Material Steel a (μm/m - °C) 11.7 25.5 Aluminum Area (mm) 800 mm 800 mm A. Force supported by the steel members (in Newtons) B. Force supported by the aluminum member (in Newtons) 2100 3000 Steel 550 mm
