Transcribed Image Text: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
