A rail road track is laid at a temperature of 10^oC with gaps of 0.007 m between the ends of the rails. The rails are 20 m long. Coefficient of thermal expansion is 11.25 x 10^-6C. Modulus of elasticity = 200 000 MPa. Which of the following gives the actual deformation of the rails that will result from a temperature of 65^oC.
