A brass rod is stress free at room temperature (20 Deg. C) It is then heated up, but prevented from lengthening at its ends by external forces. At what temperature does the stress in the rod reach -172 MPa? Assume the modulus of elasticity is 100 GPa, the linear coefficient of thermal expansion is 20 x 10^-6/Deg. C.
