Steel train rails are laid in 14.0-m-long segments placed end to end. The rails are laid on a winter day when their temperature is -5.0 ∘C. How much space must be left between adjacent rails if they are just to touch on a summer day when their temperature is 33.0 ∘C? If the rails are originally laid in contact, what is the stress in them on a summer day when their temperature is 33.0 ∘C? Please answer both questions
3. Steel railroad rails 18,2880 m long are laid on a winter day when the temperature is -6,00 °C. How much space must be left between rails if they are just to touch on a summer day when the temperature is 43 °C? (4)
QUESTION 4 What should be the separation between successive 40 feet steel rails (laid end to end) to allow for expansion if they are laid when the temperature is 30°F and the maximum temperature reached is 120°F?
The 40-ft long A-36 steel rails on a train track are laid with a small gap between them to allow for thermal expansion. Determine the total required gap, 2*6, so that the rails just touch one another when the temperature is increased from T1 -20°F to T2 90 °F. If the rails were installed at -20 °F with this gap, what would be the axial force in the rails if the temperature were to rise to T3 = 110 °F....
A railroad track la made of individual rails of steel each 29 feet in length. By what length would one rail change from a cold winter day when the temperature is -10 degree Cto a hot summer day at 30 degree C?

tension), when the whole system is at 0 °C. What is the tensile stress in the steel wires when the temperature of the system is raised to 300 °C?

How much does a 100 m piece of steel train track expand in Wyoming as the temperature swings from –40C in the dead of winter to 29.4C on a hot summer day? The coefficient of linear expansion for steel is 13.0 x 10^–6 K^–1.
During the construction of the LRT railroad track, hot rolled structural steel A36 of 10-m-long rails were used. The steel rails were laid on the track with a 5-mm gaps between the rails during the night when the temperature of the steel was 20°C. Determine the normal stress in the steel rails when the temperature of the steel is 40°C. E = 200 GPa and a = 11.7 x 10-6 m/(m °C)
