Two 1-mm diameter wires support the rigid bar as shown. Initially, the 300 mm long rigid bar is horizontal. Determine the value of dimensions a and b so that when the load is applied in the bar, the bar will remain horizontal. After the load is applied using the computed values of a and b, the temperature increases by 15 degrees. What will be the angle of the bar with respect to the horizontal after the temperature change? Use E = 200 GPa. 100 cm 75 cm Rigid bar 100 N
