Question
Transcribed Image Text:A three bar suspension system shown below is assembled at an ambient temperature of 20 °C. Determine the
axial stresses in each bar after a force F = 105 kN is applied to the rigid platen and the temperature is
increased by AT = 70 °C. The bars labeled A are fabricated from aluminum with a cross-sectional area of
A₁ = 820 mm² and the bar labeled B is fabricated from stainless steel with a cross-sectional area of
A, = 1285 mm². All bars have an initial length L = 2.3 m.
Note: Express tensile stresses as positive (+) and compressive stresses as negative (-).
