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

A segment of steel railroad track has a length of 30.000 m when the temperature is 0.0°C. (a) What is its length when the temperature is 40.0°C? SOLUTION Conceptualize Because the rail is relatively long, we expect to obtain a measurable increase in length for a 40°C temperature increase. problem Categorize We will evaluate a length increase using the discussion of this section, so this part of the example is an analysis Use AL aLAT and the value of the...

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....
