A compound bar is constructed from three bars 50 mm wide and 12 mm thick fastened together to form a bar of 50 mm width and 36 mm height. The middle bar is made of Aluminum alloy for which E-70 GPa and the outside bars are made of Brass with E-100 GPa. A) If a Compressive Load of 15 KN is applied to the compound bar, find the stresses in the brass and aluminum.

Question
Q2 A compound bar is constructed from three bars 50 mm wide and 12 mm thick fastened together to form a bar of 50 mm width and 36 mm height. The middle bar is made of Aluminum alloy for which E=70 GPa and the outside bars are made of Brass with E=100 GPa. A) If a Compressive Load of 15 KN is applied to the compound bar, find the stresses in the brass and aluminum. B) Determine the temperature at which the total stress in one bar will be zero, find also the total stress of the other bar.
