A railroad track is laid at a temperature of 10℃ with gaps of 0.008 m between the ends of the rails. The rails are 20 m long. Coefficient of thermal expansion is 11.25 x 10-6/℃. Modulus of elasticity = 200,000 MPa. a.) Give the actual deformation of the rails that will result from a temperature of 65℃, b.) Give the corresponding strain due to this deformation, and c.) Give the thermal stress if they are prevented from buckling
