THREE:Considered mechanically as a means of handling material, the human hands are capable of exerting force in any direction, vertically, horizontally, or at any angle, moving at various rates of speed, as the conditions may require, and with varying force within the limits of human strength. These functions enable us to pick up or lay down a weight slowly and carefully, to transport it at a rapid rate to save time, to move it in any direction, and without the least waste of power, except in the case of carrying small loads, when the whole body has to be moved, as in ascending or descending stairs. The power travelling cranes, that are usually employed in machine-fitting establishments, are perhaps the nearest approach that has been made to the human frame in the way of handling mechanism; they, however, lack that very important feature of a movement, the speed of which is graduated at will. It is evident that in machinery of any kind for handling and lifting that moves at a uniform rate of speed, and this rate of speed adapted, as it must be, to the conditions of starting or depositing a load, much time must be lost in the transit, especially when the load is moved for a considerable distance. This uniform speed is perhaps the greatest defect in the lifting machinery in common use, at least in such as is driven by power.And the how and the why.

FORE:It was not, however, in any of these concessions that the Stoics found from first to last their most efficient solution for the difficulties of practical experience, but in the countenance they extended to an act which, more than any other, might have seemed fatally inconsistent both in spirit and in letter with their whole system, whether we choose to call it a defiance of divine law, a reversal of natural instinct, a selfish abandonment of duty, or a cowardly shrinking from pain. We allude, of course, to their habitual recommendation of suicide. ��If you are not satisfied with life,�� they said,31 ��you have only got to rise and depart; the door is always open.�� Various circumstances were specified in which the sage would exercise the privilege of ��taking himself off,�� as they euphemistically expressed it. Severe pain, mutilation, incurable disease, advanced old age, the hopelessness of escaping from tyranny, and in general any hindrance to leading a ��natural�� life, were held to be a sufficient justification for such a step.71 The first founders of the school set an example afterwards frequently followed. Zeno is said to have hanged himself for no better reason than that he fell and broke his finger through the weakness of old age; and Cleanthes, having been ordered to abstain temporarily from food, resolved, as he expressed it, not to turn back after going half-way to death.72 This side of the Stoic doctrine found particular favour in Rome, and the voluntary death of Cato was always spoken of as his chief title to fame. Many noble spirits were sustained in their defiance of the imperial despotism by the thought that there was one last liberty of which not even Caesar could deprive them. Objections were silenced by the argument that, life not being an absolute good, its loss might fairly be preferred to some relatively greater inconvenience.73 But why the sage should renounce an existence where perfect happiness depends entirely on his own will, neither was, nor could it be, explained.These are but a few of many influences which tend to irregular cooling, and are described with a view of giving a clue from which other causes may be traced out. The want of uniformity in sections which tends to irregular cooling can often be avoided without much loss by a disposition of the metal with reference to cooling strains. This, so far as the extra metal required to give uniformity to or to balance the different sides of a casting, is a waste which engineers are sometimes loth to consent to, and often neglect in designs for moulded parts; yet, as before said, the difficulty of irregular cooling can in a great degree be counteracted by a proper distribution of the metal, without wasting, if the matter is properly understood. No one is prepared to make designs for castings who has not studied the subject of cooling strains as thoroughly as possible, from practical examples as well as by theoretical deductions.
