At a temperature of 9°C, a 2-mm gap exists between two polymer bars and a rigid support. Bars (1) and (2) have coefficients of thermal expansion of t1 = 102 x 10-6 /°C and t2 = 66 x 10-6/°C, respectively. The supports at A and C are rigid. Determine the lowest temperature at which the 2-mm gap is closed.
