So how do they do it on aeroplane wings, they stretch and waft (bend)
about in the breeze a lot, and can cope with temperature extremes and
expansion.



I remember visiting a friend who had just finished building his own
house in wales and was enjoyng his recently installed central heating.

All of a sudden there was a loud bang on investigation it was found that
his ledge and braced doors which he had lovingly glued together had
split in two right down the centre board.

There had been no where for them to adjust to the drying atmosphere. the
stress must have been phenominal
