Steel train rails are laid in 12.0-m-long segments placed end to end. the rails are laid on a winter day when their temperature is −9.0∘c. (a) 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? (b) 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?
