There is a gap of δ = 0.05cm between the steel and copper bars seen in the figure. i) When the ambient temperature rises to 200oC, will there be a reaction force in the bearings? ii) If there is a reaction force, calculate the reaction forces RA and RB at points A and B. The cross-sectional area of ​​both bars is equal and 5cm ^ 2.   Materials; Modules of Elasticity: E Steel = 210 GPa            E Copper = 120 GPa Expansion Coefficients: α Steel = 12.10-6 1 / 0C    α Copper = 16.10-6 1 / 0C
