The composite bar shown is firmly attached to unyielding supports. An axial load P=200 KN is applied at C towards A at 20°C. (a) Find the stress of segment 1 at 60°C in MPa. (b) Find the stress of segment 2 at 60°C in MPa. (c) Determine the temperature in °C corresponding to equal stresses in segments 1 and 2. The properties of materials are, segment 1: B-11.7x10-6/°C, E=200 GPa, and A=1200 mm², segment 2: B=23x10-6°C, E=70 GPa, A=900 mm².
