Mike Greenland  asked the Naked Scientists:
   Thinking of the building of the new aircraft carriers....they have been built in different locations So a large section built in Portsmouth at say 20 degree.  And a large section built in Scotland at 15deg. These are then joined. Given the very large size thermal expansion must be a factor. How do they measure this at different temperatures to ensure they fit?

What do you think?

Mutiply the linear dimensions by the expansion coefficient, or rely on the elasticity of the components.

or rely on the elasticity of the components.
