The Sports Centre at Meadowbank provides a range of facilities for outdoor and indoor sports and its aim is to act as a centre for the people of Scotland, particularly those of Edinburgh.
The objective of this study is to analyse an annular slab fixed at the outer edge and supported by equally spaced columns on the inner edge. The thin plate theory is used
in this analysis. The results are presented in the forms of a table and charts which show that deflexion and stress resultants decrease as the ratio of the inner radius to
the outer radius increases. The number of columns, with the range of four to sixteen, has not much effect on maximum radial bending moment, but the maximum magnitudes of the other stress resultants and deflexion decrease as the column number increases. Reducing the column width increases the shearing forces and the transverse bending moment. However, the deflexion and the radial bending moment are insensitive to the variation of the column width.
Mr. H. Hitch: It is our belief in the aircraft industry that we have been involved in perhaps a rather higher measure of innovation over the last few years than other industries. Are we adequately conscious of the implications of this innovation? On the moral issues the main feature of our concern is that we reckon that we have no right to introduce to the general public any new device-I am thinking of an aeroplane-which is less safe than the standard of safety existing at the time. That does not mean, of
course, that there is no possibility of innovation, but it does mean that when there is innovation the responsibility for safety and the complete onus of satisfactory
operation is on the designer and the manufacturer and to an extent the operator. I understand that your industry splits these functions amongst different organizations. With ours the only split is with the operators. Some battles go on there-the operator blames us and we blame the operator-and, of course, it is always the operator’s fault. (I am a manufacturer!)
