Question 1: A steel step bar ACB with circular cross is held between rigid wall and loaded by a axial force P at mid length (Fig. 3). Given that steel has a young modulus of E=200 GPa and thermal expansion coefficient of α = 26.5 X 106/°C, d1 = 25 mm, d2 = 30 mm and L = 1.5 m. Determine, B Fig. 3 a) If P = 2 kN, calculate the stress acting in sections AC and CB. b) If there is no force P (P = 0 KN) and there is an increase in temperature of 35°C. Determine the forces acting in wall A and B.
