A railway line is laid so that there is no stress in the rails at 8°C. The rails are 30 m long. Take temperature coefficient as 12 x 10-6/°C and modulus of elasticity of rail material as 2 x 105 MPa. The expansion allowance is 12 mm per rail. The maximum temperature rise to have no stress in the rails is
