The equation of state for a solid elastic bar of length L, subjected to a tension t, and with temperature T constitutes a thermodynamic system where the thermodynamic variables are: (t, L, T) and only two of them are independent. We have an equation that relates these variables: T = KT. CE ) L? L? where Lo is the length of the bar when the tension is zero and K is a constant. a) Is this equation consistent with the zeroth law of thermodynamics? b) If your answer is negative, state the reasons for your conclusion. c) If the answer is positive, find the differential form for the temperature in terms of the Young's modulus and the coefficient of thermal expansion Lər Y Y-Q), a -1 ). m where A is the cross-sectional area of the bar.
