Will Your Paraboloid

Keep Out The Rain?

The roofs of many houses in the Islands are often torn off simply by suction during cyclones.

But some chaps in Tedding ton, Middlesex, England, at the National Laboratory, have been busy lately making artificial cyclones so that you may keep not only your head, but your roof, in the next big blow.

Wind tunnel tests on model houses may be used to achieve a roof design which will resist cyclonic suction.

A shape of roof known as “hyperbolic paraboloid” has been suggested for this, as it pro vides considerable structural ad vantages and can be produced from small quantities of low grade timber.
