Question details

Need help finding F1 can't seem to get the correct answer. M5.14 Coaxial bars with temperature change scenes 200 mm ΔΤ 50 °C 80 GPa 17.7 x10-6/°C 250 mm2 200 GPa 15.7 x10-6/°C 5100 mm(1) 2300 mm 2300 mm 2 answers kN 6.24 P 25 kN A rigid horizontal bar ABC is supported by three vertical rods (properties given). The system is stress free before the load is applied. After the load P is applied, the temperature of all three rods is raised by the indicated AT. Determine: o the internal force in rod (1) o the normal stress in rod (2) o the normal strain in rod (1) o the downward deflection of the rigid bar at B σ2 (MPa) 62.48 494.9 +tension compression 2.524
