Mars Base One: Creating a Permanent Presence on the Red Planet (Springer Praxis Books / Space Exploration)

Martin J.L. Turner


  Mars Base One: Creating a Permanent Presence on the Red Planet (Springer Praxis Books / Space Exploration)  Martin J.L. Turner  The first mission to Mars raises the question: How will a permanent base on Mars be established? Although this is some time ahead, the opportunities and challenges posed by Mars Base One are already clear: the great distance from Earth; the necessity for self sufficiency; the challenges of long term living on Mars; how to establish a two way traffic between the planets; minimise the cost of maintenance from Earth; and importantly, keep political support over a long period. These are all generic challenges with which we are familiar, or to which there are familiar and well tried solutions for terrestrial bases and colonies. To translate these solutions to the Mars base requires the application of known science and engineering. Focusing on the near future, the theme of the book will be how to establish a base on Mars and maintain it with minimum cost and risk as well as examining future life in the base, what colonists will do there, the possibilities of trade and export, legal issues,...  книги, книжный магазин, интернет-магазин The first mission to Mars raises the question: How will a permanent base on Mars be established?

Calculation Of Columns: A Practical Application Of The Theory

Theodor Nielsen


  Calculation Of Columns: A Practical Application Of The Theory  Theodor Nielsen  Calculation Of Columns : A Practical Application Of The Theory, BY THEODOR NIELSEN. EXPERIMENTS and calculation show that the centre line of a column will, if deflected, assume a wave line, and the free length will be cotisidered as the distance between two consecutive points of contraflexure, this being the length of a column with ideal pin ends. The first step in all column calculations is to deduce the free length from the actual length, and it is also the weak point of such caIculations, as the Bee length depends upon the nature of the fixing of the ends which may even cause some eccentricity of the loading. In case where any doubt exists it is better to assume a greater free length, say full length, of the column even if the ends are held. As a guide the following will prove useful, but much depends upon individual judgment. Both ends free the free length G L is purely ideal, but very often allowed.  книги, книжный магазин, интернет-магазин Calculation Of Columns : A Practical Application Of The Theory, BY THEODOR NIELSEN.
