0 a weakness that develops in metal structures that are used repeatedly
The type of fuel can be one of these considerations, but there are others, such as climatic conditions, possible mechanical failures, certain stresses that may develop, associated with metal fatigue.
But even more worrying is the fact that there is in some cases a problem of metal fatigue in the trains themselves, some of which are 30 years old.
The same applies to the study of metal fatigue, alloys, corrosion, propeller design, wireless telegraphy and telephony, and meteorology.
We could argue about this matter in terms of metal fatigue.
If it is not an engineering problem, might it not be—heaven help us—a metallurgical, metal fatigue problem?
In some quarters the view has been expressed that there is a danger of metal fatigue in them.
No matter how good the material and careful the design, one cannot guard against human error and metal fatigue.
It is, therefore, too early to say whether this metal fatigue was a contributory factor in the accident.
