THREE:"'4. With regard to the arms of the German soldiers, it is true that the wounded men had none with them, but I have distinctly stated that the crowd consisted of soldiers who belonged to the lightly wounded and of soldiers belonging to the Landen garrison. These latter had been told off to guard the station and the platforms and maintain order. It is possible that they had also to prevent the wounded from moving about on the platforms, but in that case they did not stick to their task, because everybody was free to go where he liked, and I myself did the same. That these guards did not guard anything at all at the moment is proved by the fact that the above-mentioned civilian was able to come near the riot, although he had to pass a number of platforms. That the soldiers belonged to the Landen garrison229 and had to do sentry-go is proved by the fact that they had their bayonets on their rifles.Attention has been called to this case as one wherein the conditions of operation obviously furnish true data to govern the arrangement of machinery, instead of the determinable strains to which the parts are subjected, and as a good example of the importance of studying mechanical conditions from a practical and experimental point of view. If the general diameter of a shaft is based upon the exact amount of power to be transmitted, or if the diameter of a shaft at various parts is based upon the torsional stress that would be sustained at these points, such a shaft would not only fail to meet the conditions of practical use, but would cost more by attempting such an adaptation. The regular working strain to which shafts are subjected is inversely as the speed at which they run. This becomes a strong reason in favour of arranging shafts to run at a maximum speed, provided there was nothing more than first cost to consider; but there are other and more important conditions to be taken into account, principal among which are the required rate of movement where power is taken off to machines, and the endurance of bearings.
